This thesis project tends to create one unique database of the built heritage of Vimercate, first as a city and then as a single object, all equally important to create a proper system in service to all stakeholders: from the municipality, university, students to the locals and single enthusiast. The database is imagined as an interactive map, that can educate, but also to inform and point to the ways of reconstruction and protection. The map can provide all historical and contemporary facts, documentation, photos and projects, creating a timeline easier to manage and to comprehend. Software used for this project is free and open QGIS program, but in the future the map should be also accessible online.
