The three-dimensional reconstruction of the city of Bologna in the second half of the 16th century is based on the fresco representing the city situated in the apostolic buildings in the Vatican and commissioned by Pope Gregory XIII in 1575. The fresco represents a perspective view of the city in its complete urban development within the third circle of city walls. The three-dimensional reconstruction was made using an open-source 3D modeling software program (Blender), and concerns the whole urban area represented in the Vatican fresco. The 3D reconstruction was also based on the urban cadastral survey made by the papal state in 1835, in order to cross reference the virtual reconstruction with a reliable topographic map that was chronologically close to the Vatican source. The 3D city model of Bologna in the late 16th century was also tested on a 3D engine (Unity) to create an interactive virtual environment where a user can move about the virtual city in real time. The current state of the project allows the user to navigate the whole area of Bologna as it was depicted in the Vatican fresco. Another phase of the work focused on the reproduction of building materials and on the creation of the digital terrain model -DTM- (based on current spot heights and contour lines data) with vegetation reproduced in the pictorial decoration. The goal of the project is to obtain a dual-purpose model which can be used in university teaching to visualize the progress of Bologna’s transformation from antiquity until the Renaissance, through the production of a GIS application that will provide a visualization of the city’s historical documents. This achievement will allow a large audience interested in cultural heritage to be reached. In regard to cultural tourism, it will be possible to create customized itineraries as well as mobile and tablet Apps.

Abstract
The three-dimensional reconstruction of the city of Bologna in the second half of the 16th century is based on the fresco representing the city situated in the apostolic buildings in the Vatican and commissioned by Pope Gregory XIII in 1575. The fresco represents a perspective view of the city in its complete urban development within the third circle of city walls. The three-dimensional reconstruction was made using an open-source 3D modeling software program (Blender), and concerns the whole urban area represented in the Vatican fresco. The 3D reconstruction was also based on the urban cadastral survey made by the papal state in 1835, in order to cross reference the virtual reconstruction with a reliable topographic map that was chronologically close to the Vatican source. The 3D city model of Bologna in the late 16th century was also tested on a 3D engine (Unity) to create an interactive virtual environment where a user can move about the virtual city in real time. The current state of the project allows the user to navigate the whole area of Bologna as it was depicted in the Vatican fresco. Another phase of the work focused on the reproduction of building materials and on the creation of the digital terrain model -DTM- (based on current spot heights and contour lines data) with vegetation reproduced in the pictorial decoration.
