The Bargello Museum is located in the impressive Palazzo del Bargello, a fortress with powerful embattlements which surround the austere facade. Begun in 1255, the building was the headquarters of the Capitano del Popolo and later of the Podestà and Council of Justice. In 1574, it became the living quarters for the Captain of Justice (chief of police) and was used as a prison.Despite a series of alterations and additions which altered the original plan during the 14th and 15th centuries, the palace preserved its pleasant severity, best seen in the beautiful courtyard, the balcony and the large hall on the first floor. A covered staircase, built in the 14th century, leads to an upper loggia. The walls of the courtyard are covered with dozens of coats of arms of the various Podestà and Giudici di Ruota (judges).
