Built as the residence of the Trinci family - rulers of the city between 1305 and 1439 - this palazzo later became the residence of the papal governors. The current palace was built between the fourteenth and fifteenth centuries over pre-existing buildings and it was damaged several times through the years, including by the World War II bombings, it underwent important restorations during the twentieth century. The facade was built in the nineteenth century on a project by architect Odoardo Poggi, modified by Sigismondo Ferretti. A staircase leads up to the Loggia, with frescoes representing the legend of Rome’s foundation. The rooms of the noble floor branch off from here; the Chapel is decorated with the stories of the Virgin by Ottaviano Nelli from 1424. The Hall of Arts and Planets is accessed by an arched door: here are represented the liberal arts, the seven planets and the seven ages of man, each symbolized by an hour of the day. In the Hall of the Giants, originally used as a public hall, the grandeur of Rome is celebrated with frescoes of examples of greatness and virtue, recently attributed to Gentile da Fabriano. Today the Palace is home to the City Museum.
