The fortress of Gualdo Cattaneo
The fortress is certainly the most important monument of Gualdo Cattaneo.
Its construction started in 1494, it was designed according to the military standards of the time, when the advent of artillery was radically changing the aspect of all defence structures.
The fortress, called “Of the Borgias” in honour of Pope Alexander VI, was completed in 1500 and different skilled workers contributed to its construction.
