#### 3.3.2 Proposed Spaces
This initiative not only aims to generate energy for lighting poles and restaurants within the garden but also produces biol as fertilizer, thus promoting sustainability [50]. In the educational framework, the figure includes buildings dedicated to the Botanical Research Center and an Agricultural and Ethnobotanical School, emphasizing the importance of education and scientific research in botany, biology, and ecology. This approach is further enriched by considering the information provided by INGEMMET (Geological,  
Figure 17: Urban retreat view. Figure 18: Botanical garden view. Mining, and Metallurgical Institute) and its National Vegetation Cover Map [51], since they become an essential tool for the selection of species, prioritizing those that require protection and conservation such as Cadillo (_Centreus chinatus_), Molle (_Schinus molle_), Fresno (_Fraximus_), Ambrosia (_Ambrosia peruviana_), Magueyes (_Agave americana_), Iresine (_Iresine herbstii_), Llanet (_Plantago major_), and Araucaria (_Araucaria araucana_). Peru harbors 70% of the world's biological diversity, highlighted by its position as the country with the highest number of species of diurnal butterflies in the world, totaling close to 4000 species [52]. That is why it is optimal to implement a butterfly house in the green corridor for the intensive production and conservation of butterflies, where live adults are obtained from early stages or early stages are produced from adults capable of continuing to reproduce in perfect condition in a controlled environment. This promotes the sustainability of biodiversity through research, training, and education, always seeking a balance between conservation and sustainable development [53]. Figure 19 highlights the presence of strategically distributed butterfly houses along the green corridor, with a total of three. These butterfly houses, covering an area of 175 m\({}^{2}\) each, will initially house 220 butterflies classified into six different species: _Morpho helenor_, _Heliconius dors_, _Phoebis philea_, _Caligo ilioneus_, _Battus polydamas_, and _Consul fabius_. As the project develops, a gradual increase in the number of species is expected, thus contributing to the diversification of the environment. Additionally, this space not only aims to be a sanctuary for butterflies but also an educational and environmental awareness tool for the population of Cuzco, strengthening their connection with the environment and promoting local identity through conservation and awareness panels, sculptural furniture, and photographic spots. The butterfly house will also highlight the importance of host plants present in its environment. Among the included plant species are _Aristolochia_ sp., _Piper_ sp., _Cassia_ sp., _Semua elata_, _Asclepias_ sp., _Passifora auriculata_, and _Musa_ sp., among others. These host plants not only serve as landscape elements but they also provide the necessary habitat for the reproduction and development of butterflies, thus reinforcing the interrelationship between the flora and fauna of Cuzco [54].

Viewing Tower In addition to being a recreational spot for the residents of Cuzco, the viewing tower serves as an attraction for visitors, promoting the creation of public spaces in areas of the green corridor that may not have been fully utilized. The tower also provides amenities for visitors, such as resting areas, common zones, disinfection areas, and spaces for souvenir sales. Figure 20 depicts the incorporation of viewing towers along the green corridor. These structures, each with an area of 100 m\({}^{2}\), will be strategically distributed in six specific points of the terrain, allowing visitors to fully enjoy the landscape and various areas of the green corridor. Each viewing tower, with a height of 20 m and five floors of 4 m each, features a functional layout that addresses current needs.
