It was built in the middle of the thirteenth century as the residence of the chief magistrate of the city, the Capitano del popolo, or Podesta, first appointed soon after the return of the Guelphs in 1251, and it so remained, with such natural Florentine vicissitudes as destruction by mobs and fire, for four hundred years, when, in 1574, it was converted into a prison and place of execution and the head-quarters of the police, and changed its name from the Palazzo del Podesta to that by which it is now known, so called after the Bargello, or chief of the police.
It is indeed fortunate that no rioters succeeded in obliterating Giotto's fresco in the Bargello chapel, which he painted probably in 1300, when his friend Dante was a Prior of the city.

Giotto introduced the portrait of Dante which has drawn so many people to this little room, together with portraits of Corso Donati, and Brunetto Latini, Dante's tutor.

Whitewash covered it for two centuries.

Dante's head has been restored.
It was in 1857 that the Bargello was again converted, this time to its present gracious office of preserving the very flower of Renaissance plastic art.
Passing through the entrance hall, which has a remarkable collection of Medicean armour and weapons, and in which (I have read but not seen) is an oubliette under one of the great pillars, the famous court is gained and the famous staircase.

Of this court what can I say?
Its quality is not to be communicated in words; and even the photographs of it that are sold have to be made from pictures, which the assiduous Signor Giuliani, among others, is always so faithfully painting, stone for stone.
