The Fortress of Girifalco is located in Cortona, near Arezzo. The fortress is in a dominant position over the city and the construction of the fortress dates back to 1258. The fortress was used as a military and strategic point of the city. Its location was a great bastion of defense. In 1556 for Cosimo I de 'Medici, the architect Francesco Laparelli and military engineer Gabrio Serbelloni collaborated to design four bastions and the ravelin. During the sixteenth century the medieval walls to fortify the city were replaced. In the following centuries it was used as a prison, shelter and post war. For example, during World War II the Germans settled a radio transmitter, which also exploited the allies later. Only in 1959 it was possible to restore the fort and make it accessible. In 2010 it ended the recovery of the bastion of Santa Maria Nuova to improve accessibility. Inside the walls there is a large garden, the internal courtyard and the Palazzo del Capitano. At the entrance of the fortress are visible spaces of the wash deck and a secret staircase connecting the upper floor. Today the fort houses temporary exhibitions, events and conferences.
