###### Abstract
For example, the Roma Reborn project generated various versions of a virtual ancient Rome in 320 AD. The Roma Reborn 2.0 project utilized the manual creation of detailed monument models by teams of computer graphics experts and archaeologists, while the urban environment comprising 7000 buildings was generated procedurally. The process involved starting from polyhedral volumes obtained by scanning a scale model of the city [15]. Similarly, a 3D model of the city of Prague was generated using an algorithm of point segmentation applied to an existing scale model [16]. Another case involves the reconstruction of French cities, Toul, Aire-Sur-la-Lys, and Saint-Omer, using images of city models from the collection of fortified cities in France made between the 17 th and 19 th centuries (plans-reliefs). Buildings were identified and reconstructed based on a parametric definition, with automated identification of building types, roof plans, chimneys, textures, and parameter values. A 4D model of the city of Hamburg utilized data sources from a wooden model from 1644 and one of the first official plans of the city from 1859. The reconstruction process involved the automated generation of building plans, followed by the facade, roofs and building components. The typology of gabled roofs and buildings with four basic faces was assumed for the automation of the reconstruction [17]. Additionally, a recreation of the city of Nafplio in the 19 th century was developed for an educational application. The authors addressed the challenge of modelling buildings that no longer exist today from graphic documents such as photographs, drawings, and paintings, as well as buildings that have undergone interventions after the recreated period [18]. The European Union has recognized the importance of this research area and funded several projects that promote the creation of digital content that primarily reconstructs archaeological spaces, historical places, or objects that are difficult to access or no longer exist [18]. This work focuses on the 3D reconstruction of the city of San Cristobal de La Laguna based on a map created by [PERSON]. While there have been previous 3D reconstructions related to cultural heritage in the city (a convert [19] and a house [20]), our project is the first historical 3D reconstruction of an entire city in the Canary Islands. We complemented [PERSON]'s map with other historical sources to form a visual description of the city in 1588 that can be extended to the rest of the cartography of that time in the Canary Islands as well as other cities. We present our workflow, the difficulties encountered, and the solutions provided. Our approach is different from other map-based reconstruction workflows [21], as it deals with maps from a time when topographical techniques were not yet developed. The main contributions of our work are:  
1. A 3D reconstruction of the UNESCO world heritage city of San Cristobal de La Laguna in the 16 th century. 2. A workflow for the 3D reconstruction process where the unique source of visual information is a map, and several modelling techniques have to be integrated. 3. A decomposition of the houses in the map in terms of basic constructive elements and a generative model of the houses in the city in terms of these elements. 4. A house placement method using the block shapes of the city. The rest of the work is structured as follows: in Section 2, the methodology used to build the 3D reconstruction is presented, including a detailed discussion of all its steps. In Section 3, the results of the reconstruction of the city and its surroundings are shown, while in Section 4, a discussion of the work is given and some future works are presented. Finally, in Section 5, we outline the conclusions of this work.
