Published: June 2023

O uso da cannabis para o tratamento da epilepsia sempre teve papel de destaque no tratamento dos casos dessa doença, isso não acontecia por acaso. De acordo com um relatório de revisão crítica da Organização Mundial da Saúde (OMS), essa substância poderosa é benéfica para pessoas com doenças que afetam o sistema nervoso e as sinapses cerebrais. Esse reconhecimento se deve a um grande número de estudos que apontam para a eficácia dos canabinoides, que podem ser usados ​​como anticonvulsivantes e neuroprotetores. A epilepsia é uma doença que afeta o sistema nervoso central (SNC) e o cérebro. O sintoma mais óbvio são as convulsões, que podem ser clônus ou clônus tônico e, em alguns casos, podem causar perda de consciência. No Brasil, cerca de 1% a 2% da população sofre de epilepsia, que pode afetar pessoas de todas as idades. É uma das doenças mais comuns do sistema nervoso central.Embora o CBD não tenha sido 100% aprovado cientificamente para o tratamento da epilepsia, ele foi considerado seguro e eficaz. Isso porque o óleo de canabidiol é um dos medicamentos mais prescritos e apresenta vantagens muito relevantes em comparação com os medicamentos convencionais.

Authors: He Y. , Peng N. , Li W. , Tai Y.
Published: June 2023

Abstract. The use of multiple digital technologies has addressed conventional exhibition display issues, improving public experience, and aiding in the understanding of historical changes in cultural heritage. This facilitates community sharing and international promotion. Furthermore, the promotion of novel digital application scenarios can encourage the growth of cultural consumption and the digital creativity industry. Beijing's Central Axis is a remarkable and well-preserved example of a traditional central axis in China's capital cities. It is comprised of numerous building complexes and archaeological sites located within the old city. This axis was first constructed in the 13th century, shaped in the 16th century, and continues to thrive today while remaining open to the future. By assessing its dynamic "growth" and "living" value, we have devised an innovative interpretation system plan that includes Augmented Reality Tours, immersive exhibitions in historical buildings, online exhibitions, and a series of public activities. The pilot project, implemented at the Drum Tower located at the northern end of the Central Axis, involved careful restoration and scientific transformation, accurate heritage documentation, and digital reconstruction. Digital creativity empowered and activated the historical building, achieving a comprehensive balance of conservation, utilization, and economics. The exhibition has garnered favorable feedback, particularly from the younger generation, who appreciate the combination of ancient cultural heritage themes and modern digital immersive displays.
3D SCHOLARLY EDITIONS FOR BYZANTINE STUDIES: MULTIMEDIA VISUAL REPRESENTATIONS FOR HISTORY, ART HISTORY AND ARCHITECTURAL HISTORY
Authors: Higuchi R. , Murata K.
Published: June 2023

Abstract. The Byzantine Empire has bequeathed to us a rich legacy of Christian churches, many of which possess historical and cultural significance. Unfortunately, the majority of these structures are currently undergoing a process of decay, having not received adequate preservation efforts. Moreover, the absence of collaboration between researchers in the various fields, each with their own focus on the study of Byzantine churches, presents a pressing need for dialogue and a collective response from these researchers. The region of Laconia, located in the south of Greece, is particularly in need of immediate attention, given the abundance of churches located therein. To address these challenges, the authors propose a novel approach involving the documentation of these churches in a digital format through the presentation of 3D models as scholarly editions that incorporate all available data sets in a multimedia format. This paper delineates several requisite specifications for 3D scholarly editions, which hold the key to solving the twin problems faced by Byzantine churches, namely, their protection and the scarcity of interdisciplinary collaboration amongst researchers. With 3D scholarly editions based on multimedia resources and adequate information management, it will be possible to facilitate collaboration and research between various fields of Byzantine studies, and beyond. Such efforts will serve to ensure that cultural heritage passed down from previous generations will be transmitted to future ones.

Published: June 2023

Abstract. To solve the problem that Dougong has various shapes and complex structures, the corresponding solutions are proposed in this paper. Our proposed method mainly consist of two parts. At first, the surface primitives were segmented using the machine learning (Random Forest). In this stage, the features including the curvature, normas and other features based on covariance matrix. Then, the knowledge from the construction rules were applied to label the segmented surface primitives into correct categories. The corresponding height constraint, concave-convex constraint, and symmetry constraint are proposed as the judgment conditions to mark the geometric elements belonging to the same dougong component and complete the point cloud segmentation of the dougong component. To verify the performance of our proposed method, the point cloud of a Qing-style single-arch flat-bodied Dougong was tested. The experimental results show that the classification accuracy of point cloud is 96.0%.

OPENHERITAGE3D: BUILDING AN OPEN VISUAL ARCHIVE FOR SITE SCALE GIGA-RESOLUTION LIDAR AND PHOTOGRAMMETRY DATA
Authors: McAvoy S. , Ristevski J. , Rissolo D. , Kuester F.
Published: June 2023

Abstract. LiDAR and photogrammetry are common mechanisms for the documentation of cultural heritage sites. Their outputs provide foundational primary sources for research and important engineering decisions contributing to the on-going conservation of sites and structures. Unfortunately, due to the complex nature of these data, they are rarely shared with stakeholders in their full forms. Raw data is routinely transferred to portable hard drives and forgotten at a project’s end. Digital heritage documentation, often acquired with great effort and cost, is at risk of loss (UNESCO 2003). When these data are shared, they are rarely presented or formatted in ways which enable their widespread re-use. As processing tools improve at a rapid pace, and offer new pipelines for improved reconstruction and fusion with additional data sources, it is important to preserve the data in a way which maintains all functionality and interoperability between processing platforms. It's not enough to share data or to simply make them "available." Data must be technologically and intellectually intelligible (and useful). A new system framework is required to ensure their integrity and wide-spread utility, and to democratize these data for re-use by the diverse communities of stakeholders with whose purposes fall outside the narrow scopes of a 3D documentation project’s original goals. In this paper we present OpenHeritage3D.org as a platform and framework for an open visual archive seeking to provide authoritative and democratized access to site-scale lidar and photogrammetry through data curation, file-sharing, and web-visualization systems with granular segmentation and data conversion capabilities.
ADAPTION OF INDUSTRIAL NDT PROTOCOLS BASED ON ACTIVE INFRARED THERMOGRAPHY TO THE ART CONSERVATION WORLD: THE CASE OF THE WALL PAINTING AT HERODIUM
Authors: Ovadia M. , Brook A.
Published: June 2023

Abstract. Salt weathering is one of the most detrimental agents in the deterioration of historic wall paintings. Unfortunately, it is most noticeable once it reaches the surface, and the damage has already been done. Its elusive nature and its integration into the historic structures make it difficult to accurately detect soluble salts at the sub surfaces of wall painting non-destructively. Detailed detection in a delicate artifact such as wall paintings requires custom methodology. The study's case study is the wall painting in Herodium. The wall paintings were severely damaged by salt weathering. Although great efforts were invested in restoring and protecting the paintings their state is still unstable. This study offers a new perspective on the matter utilizing the adaption of industrial protocols based on active Infrared thermography (IRT) with data processing via thermographic signal reconstruction (TSR). The study's primary goal was to optimize the inspection methodology and assist the conservation process with knowledge of soluble salt hazards hidden at the subsurface.
A SCANNER-BASED 3D MODELING METHOD OF IMPROVING THE TIMBRE OF CHINESE GUQIN BY TRANSPLANTING THE BASS BAR OF THE VIOLIN
Authors: Tang Y.
Published: June 2023

Abstract. Guqin is the Chinese oldest musical instrument and intangible cultural heritage. The Tang Dynasty was the most prosperous in Chinese history, with a flourishing culture. One of the Guqin manufactured by Master Lei Wei, a notable Guqin maker in the Tang Dynasty, was recognized as a reference standard instrument and is kept in the Palace Museum in Beijing. Stradivari, a well-known Italian violin maker, has created and improved violins that no one else can surpass. Triangulation laser and CT/CBCT Scanner-Based 3D modelling data-driven analysis of the ancient musical instrument Guqin from the Tang Dynasty has been compared with the Italy Stradivari violin in a historical review perspective in this paper. After delving into the wood, spatial structure, and other aspects of the Stradivari violin, it has been discovered that the wood, paint, and inner cavity design used by the two masters during their respective heydays are strikingly similar, revealing their shared experience in creating ancient musical instruments in their countries. The bass bar of a Stradivari violin is meant to be transplanted into a Chinese Guqin prototype and get the conclusion that the timbre of the Guqin can be improved according to MATLAB spectrum analysis. This is the first time the two masters from Eastern and Western comparison analysis after the millennium.
TRACKING THE URBAN CHAMELEON – TOWARDS A HYBRID CHANGE DETECTION OF GRAFFITI
Authors: Wild B. , Verhoeven G. , Pfeifer N.
Published: June 2023

Abstract. Colourful and ever-changing: Graffiti can be considered the urban chameleon skin. At the Donaukanal (Eng. Danube Channel), Vienna's central waterway and one of the largest and most active graffiti-scapes worldwide, this metaphor applies like hardly anywhere else. Every day a multitude of graffiti is destroyed by the creation of new works. Recently, efforts have been made to mitigate this constant loss of cultural heritage along the Donaukanal by systematically documenting the graffiti, mainly using photography and photogrammetry. However, keeping track of the newly added works is very time-consuming and often like finding needles in a haystack, considering the large extent and high volatility of the monitored area. Thus, an automated graffiti change detection would significantly reduce the effort and avoid overlooking graffiti.This contribution outlines the main challenges in image-based change detection for cultural heritage and proposes a hybrid graffiti change detection method. The investigated method exploits and combines an established pixel-based change detection algorithm, the Iteratively Multivariate Alteration Detection, with a novel descriptor-based method. The latter relies on image features, rather than pixels as analysis unit and can robustly filter false alarms from the high-performing but noise-prone pixel-based approach. Overall, the results indicate that the proposed method can largely automate image-based change detection of graffiti-scapes. It can uncover graffiti-related changes and robustly distinguish them from other image differences such as shadows but tends to overlook small-scale graffiti, indicating the need for further fine-tuning.

Abstract. In recent years, LiDAR has seen an increased application in the field of archaeological documentation, as it allows for rapid acquisition of spatially dense and accurate point clouds. The three-dimensional survey and monitoring of ongoing excavations is a topic of particular interest for archaeological documentation, due to the importance of recording stratigraphy during the destructive and irreversible process of the excavation, and the challenges of obtaining complete photorealistic digital representations of the archaeological terrain. In this paper, we investigate the feasibility of obtaining in real time high-quality digital models and maps of the stratigraphy via laser scanning, aiming to establish a replicable methodology for archaeological practice. Optimal acquisition and processing scenarios are explored for both terrestrial and drone-mounted LiDAR. The application concerns two different case studies of archaeological interest with different topography. The presented research is part of the project ARCHAEORAMA–“Advanced system for multimodal Recording, Documentation and Promotion of Archaeological Work”.

Authors: Zhou Y. , Aura-Castro E. , Nebot Díaz E.
Published: June 2023

Abstract. This paper describes the Charter on the preservation of the digital heritage and it also presents the five main printing technologies, FDM (Fused Deposition Modeling), SLA (Stereo Lithography Apparatus), DLP (Digital Light Processing), LCD (Liquid Crystal Display) and SLS (selective laser sintering) technology. Besides, It presents a methodology to process the restoration of a porcelain bowl through three-dimensional scanning and FDM (Fused Deposition Modeling) and LCD (Liquid Crystal Display) 3D printing technologies. First, the porcelain bowl is scanned with the scanner. Then the modeling software is used to reconstruct the missing part that the bowl presents. Finally, the reconstructed 3D fragment model is printed, completed and chromatically reintegrated. In order to optimize this restoration method to achieve the best visual effect similar to the appearance of the porcelain bowl, different printing materials are used for testing. This type of restoration method can improve the final appearance of the intervened area, minimize the operation of the object and can also make it be shaped quickly and precisely.
VALIDATION OF FULL-RESOLUTION DINSAR-DERIVED VERTICAL DISPLACEMENT IN CULTURAL HERITAGE MONITORING: INTEGRATION WITH GEODETIC LEVELLING MEASUREMENTS
Authors: Eskandari R. , Scaioni M.
Published: June 2023

Abstract. Towards revealing the potential of satellite Synthetic Aperture Radar (SAR) Interferometry (InSAR) for efficient detection and monitoring of Cultural Heritage (CH) encouraging resilient built CH, this study is devoted to the validation of InSAR-derived vertical displacements with a full-resolution perspective taking advantage of high-precision geodetic levelling measurements. Considering the Cathedral of Como, northern Italy, as the case study, two different Persistent Scatterer Interferometry (PSI) techniques have been applied to Cosmo-SkyMed high-resolution SAR images acquired in both ascending and descending orbit tacks within the time interval of 2010–2012. Besides using the simplified approach for obtaining the vertical displacement velocity from Line of Sight (LOS) velocity, a weighted, localized, multi-track Vertical Displacement Extraction (VDE) approach is proposed and evaluated, which uses the technical outcome of Differential InSAR (DInSAR) and spatial information. The results, using a proper PSI technique, showed that the accuracy level of extracted vertical displacement velocities in a full-resolution application is ca. 0.6 [mm/year] with a dense concentration of InSAR-Levelling absolute errors lower than 0.3 [mm/year] which are reliable and reasonable levels based on the employed validation framework in this study. Also, the weighted localized VDE can significantly decrease the InSAR-Levelling errors, adding to the reliability of the InSAR application for CH monitoring and condition assessment in practice.
ROOM POINT CLOUDS SEGMENTATION: A NEW APPROACH BASED ON OCCUPANCY AND DENSITY IMAGES
Authors: Gourguechon C. , Macher H. , Landes T.
Published: June 2023

Abstract. The majority of buildings are existing and have not been constructed in a BIM process. That is why, the modelling of existing buildings becomes a major issue. Beyond the questions of maintenance or renovation with the promise of reducing the environmental impact, their modelling is of interest for documentation and valorisation. But today, while the acquisition techniques are significantly progressing, with the use of efficient laser scanners, the modelling remains manual and very time consuming. The literature is not empty of proposals to automate the process. Nevertheless, many studies are based on strict architectural hypotheses or restricted to unoccupied buildings free of furniture. This strongly limits their application field. In response to these limitations, this paper presents an innovative method retaining only verticality of walls as assumptions. It is based on occupancy and density image analysis. Tested on a wide variety of buildings, this method is very promising with very few classifications errors. Furthermore, the process is successful with dynamic laser scanning data, in cluttered environments, and applied on buildings with a non-Manhattan-World scheme.

Authors: Attenni M. , Barni R. , Bianchini C. , Griffo M. , Inglese C. , Ley Y. , Pritchard D. , Villa G.
Published: June 2023

Abstract. As part of a comprehensive survey and modelling project involving the Aachen Cathedral, this paper focuses on its oldest part, the Palatine Chapel, a domed octagonal hall supported by eight piers and enveloped by a sixteen-sided outer wall. Working on the data collected during an extensive 3D capturing campaign conducted between 2022 and 2023, this paper will focus on the conic vaults covering the ambulacrum of the 1st floor that represent quite a peculiar architectural and structural solution considering the VIII/IX century building know-how. In this framework, the Chapel's 3D point cloud has been analysed to extract the main 2D generative elements of the conic surfaces and then construct the corresponding 3D geometric models. These outputs have been compared against the captured point cloud to assess the differences between the actual vault data and the reconstructed ideal conic shapes. Finally, the method used to unfold the vaults' surfaces and create high-resolution ortho-images has been displayed.

Abstract. The project for the second competition for the Parliament of the Kingdom of Italy, drawn up between 1888 and 1889 sees Ernesto Basile (Palermo 1857-1932) as winner ex aequo. Basile's project envisages the construction of a large monumental building (182.70 m by 171.40 m), in which the three halls, the Chamber, the Senate and the Royal Sessions Hall, develop around a large central courtyard; it will not be realized due to the fall of the Crispi government in 1891, but presents, in embryo, solutions adopted in the expansion of Palazzo Montecitorio (1903 - 1918), entrusted to Basile, in which the Chamber of Deputies, still existing today, is may consider “a sort of budding, from the organism of his second Parliament Building” (Mauro, Sessa 2000b).The original drawings are kept and cataloged in the Basile Endowment of the Scientific Collections of the Department of Architecture of the University of Palermo, edited by Professor Ettore Sessa (Mauro, Sessa, 2000a; Sessa, 2014, Mauro, Sessa, 2015).In a first phase, the conjectural reconstruction and digital modeling was carried out (Avella, 2020), and in a second phase, a first 3D printing model was created, limited to the main front, which involved the design of the decomposition and assembly according to criteria respectful of architectural parties (Avella, 2021).This work presents the progress of the work, extended to the bodies containing the Chamber of Deputies and that of the Senate and the integration with Augmented Reality systems, in view of the future permanent exhibition at the premises of the Basile Endowment. The integration with Augmented Reality visualization systems stems from the desire to allow the observer to visualize the external envelope of the physical model and the internal spaces of the parliamentary halls.

Published: June 2023

Abstract. The UNESCO 2011 Recommendation on the Historic Urban Landscape promotes to map cultural significance of urban heritage from the perspectives of the general public in pursuit of social inclusion in heritage management. The user-generated information already available on social media platforms in the form of images, comments, and ratings can be considered a rich source for collecting data concerning the tourists’ image of destinations and their collective perception of urban cultural heritage. Considering the large amount of unstructured data, artificial intelligence (AI) can construct structured feature vectors therefrom and significantly aid the analysis and collation processes compared to the traditional manual approach for mapping public perception of cultural heritage. This paper presents an exploratory case study conducted in the area of Testaccio, Rome, showcasing the use of AI to map the perceived and narrated urban heritage images using social media data. An image-sharing platform, Flickr, is used to collect thousands of posts containing images and comments in the area, which are further analysed with pre-trained image recognition, natural language processing, and dimensionality reduction algorithms. Results as the urban heritage images are visualised, showing the most significant elements from a public perspective. Such a methodology provides an alternative perspective of viewing the urban heritage attributes as a collection of depicted and posted content. It can contribute as a tool for the documentation of collective attention for inclusive heritage management and local development planning during the designing and policy-making processes.
WHAT COMMUNICATION ABOUT HERITAGE CONSERVATION? A CHALLENGE FOR DIGITAL DOCUMENTATION CONTENT

Published: June 2023

Abstract. The technological methods for digital documentation and the experimental best practice standards used to document and describe the many artistic objects determine the challenges and the numerous uses of today’s cultural heritage.Because of this, it's crucial to preserve heritage by documenting it consciously and using conservation techniques that don't diminish or affect its worth. The study examines the issues we faced in disseminating all of the technical content we have, rather than focusing on the general importance of digital data for the technical staff. To share our heritage, we must make the digital legacy we have built over the last twenty years accessible. Starting from practical examples of dissemination projects in the context of conservation items, the analysis discusses an investigation into the findings and disciplinary culture that have resulted from research conducted by academics in the field of digital heritage on papers, conferences and EU projects produced and conducted between 2018 and 2022. The paper reviews the digital cultural heritage framework outlined by research up to this point.Our findings demonstrate that, despite the fact that the DCH area is constantly changing, we still primarily consider the technical side of digital without considering it as a genuine possibility for openness and sharing.

Abstract. The Middle East Technical University (METU) Ankara Campus is one of the earliest and most prominent modern-period university campuses that resulted from an architectural competition in the 1960s in Turkey. However, METU Campus, as a modern-era heritage place, faces various threats, including pressure for new urban development. In addition, the increasing number of students and contemporary educational needs require changes in the physical infrastructure and campus settings. Thus, all these threaten the tangible and intangible values of the Campus. In this regard, conserving the METU Campus requires a multidimensional approach that considers a wide range of values and problems; herein, the Geographic Information Systems (GIS) becomes a useful tool for dealing with this complex work. Accordingly, the METU Campus GIS Project [METU_GIS] was developed to document and understand the multidimensional characteristics of the METU Campus, assess its values, and propose solutions to current issues while considering its values and potentials. Accordingly, the METU_GIS defines conservation policies and strategies that ensure the conservation and sustainability of the Campus as a living modern heritage place. Furthermore, the METU_GIS is a GIS-based conservation management plan created for a modern period campus for the first time in Turkey. Hence, it became an essential basis and a tool for conserving and managing the METU Campus as a modern living heritage place. All in all, the METU_GIS proves that Geographic Information Systems (GIS) are essential tools that can be used in the documentation, conservation, and monitoring of modern heritage places.
HISTORIC STONE PAVEMENT PHOTOGRAMMETRIC 3D-SURVEY: A WAY TO GET A CATALOGUE TO PASS ON ANCIENT CRAFTS

Published: June 2023

Abstract. In Tuscany, the art of paving has never been codified in written form, being already encapsulated in knowledge based on practical experience, with specialized tradesmen and stonemasons relying on direct observation and passing on their knowledge to apprentices through repetition of gestures. The streets of Volterra, a historic town in Tuscany, are still paved with the local stone, the panchina volterrana (Volterran panchina stone). Photogrammetry techniques allow high-resolution reconstruction of 3-D pavement models and geometric representation of the macrotexture component resulting from the chiselling of the stone, as well as gaining high-resolution, high-precision geometry information along with colour information. In this way, it is possible to fully characterize the stone and generate a catalogue, which can become an operational tool for those involved in monitoring and maintaining pavements. This paper presents the methodology of photogrammetric surveying and the possibility of obtaining indices of the macrotexture of the processed surface of the stone, in terms of Virtual Mean Texture Depth (V-MTD), in analogy with the analysis of asphalt surfaces. The classification is also proposed by integrating the geometric macrotexture data with the data derived from a segmentation of the different textures obtainable for the model (diffuse, ambient occlusion). This geometric information could be then enriched by the stonemason's indications, constituting, therefore, a tool for passing on one's knowledge and experience.
3D SURVEY AND MATERIAL CHARACTERIZATION OF THE ARCHAEOLOGICAL COMPLEX OF THE STADIUM OF ANTONINO PIO IN POZZUOLI

Abstract. The presented work is an expansion of practice exercise carried out for a diploma thesis of the School of Specialization of Architectural Heritage and Landscape of the University of Naples Federico II, in agreement with the Archaeological Park of Phlegraean Fields, and illustrates the results of the 3D survey and material characterization campaign of the archaeological complex of the stadium of Antonino Pio in Pozzuoli. It is located on the western border of the Roman city of Puteoli and was built by Emperor Antonino Pio to host Eusebia, the quinquennial ludi instituted in Hadrian’s memory. After the 6th century, the area was gradually abandoned until it was buried by volcanic ash in 1538. Since the start of the 21st century, archaeological excavations were performed, together with the first series of safety works on the structures and excavation fronts.This research work fits in the phase of analysis and material characterization, which is preliminary to the elaboration of a restoration project. It consisted of the 3D survey of the structure with laser scanning and photo modeling techniques through aerial drone shots and was aimed at the individuation of the construction typologies and ongoing decay phenomena.The continuous reference between the results of the survey and those from the comparative analysis of historical and archival documentation has allowed the reconstruction of its architectural history and the sequence of its recent restorations, hence defining an integrated and implementable picture, which is necessary for the realization of suitable strategies of conservation and fruition.

Abstract. 3D digitisation is essential to enhance knowledge and conservation processes for Cultural Heritage (CH). However, movable heritage collected in museums, e.g., archeological finds, statues, coins, and musical instruments, often consists of highly reflective surfaces and/or featureless textures. The aim of this work is to stress the Structure from Motion Dense MultiView Reconstruction (SfM-DMVR) of objects, whose optical properties are challenging to this image-based technique. To improve the results obtained by SfM-DMVR standard acquisition workflow, this study exploited the potential of combining Noise Function Pattern (NFP) projection and light Cross Polarization (CP). Moreover, High Dynamic Range (HDR) image reconstruction was tested on images acquired according to different CP angles. The SfM-DMVR of a texture-less shiny ceramic object was then compared to the one obtained by a structured light triangulation scanner, the most reliable tool for such surfaces, but unfortunately quite expensive. The advantages and limitations of the presented method are discussed.

Abstract. The new technologies are changing every aspect of our life, socially and workwise. In the same way, digital tools are becoming increasingly important to protect, preserve, and valorise cultural heritage. The digitalization of the archive’s documents and ancient books, the realisation of augmented reality apps for museums, or even the creation of virtual realities set in cultural or landscape environments that are protected or not open to visitors, are examples of the use of the new technology in the field of cultural heritage.In this context, the projects “Cosmic Pages” and “Touch the Sky” were developed. One of the main goals of these projects is the realisation of the virtual exhibition “Look up!”. It is an effective virtual tool aimed at enhancing and giving maximum dissemination of the collection of the stellar atlases, cometographies and selenographies preserved in the Observatories of the Italian National Institute for Astrophysics. This virtual exhibit was conceived and realised allowing the visitors to discover, explore, and understand how our knowledge of the cosmos, the Moon and the planets have evolved and changed with the time. Using the most advanced technologies, virtual reality, 3D models, videos etc., visitors can explore the scientific and cultural contents of the stellar and cartographic atlases.
