Fort Saint-Jean in Marseille

Fort Saint-Jean is of great importance in Marseille because this site is the founding point of the city. A reconstruction of this building and the Saint Laurent church is undertaken using modelling techniques to better understand its history, because it was transformed and destroyed so many times in 26 centuries.
Myriame Morel, historian and curator of the MuCEM, and Michel Florenzano, architect and former director of the MAP, share their research outcomes on different sources of documentation (iconographies, architectural surveys, archaeological findings, etc.) and the complexity of their investigations because of the very fragmentary and scattered sources.
Livio De Luca, architect director of the MAP, presents the laboratory and in particular the Fort Saint-Jean project which has made it possible to develop an original approach based on the mapping of current data with those of the past, and to experiment with a three-dimensional acquisition system.
Nicolas Nony, historian, shows the interface which makes it possible to generate automatically 3-D colored-dot clusters from photographs.
Romain Balza, architect, describes the photomodelling methodology used to produce a complete and textured 3D model.
