The Piazza dei Ciompi, situated north of Piazza Santa Croce and close to Piazza Sant'Ambrogio, hosts the Loggia del Pesce, designed by Giorgio Vasari and the house of Lorenzo Ghiberti.
In 1378 Florentine wool carders - the so-called ciompi, rose up in the district of Santa Croce in favour of the recognition of the rights of the most humble labourers. The revolt is known as the Tumulto dei ciompi (revolt of the ciompi).

Today, Piazza dei Ciompi is the seat of a popular flea market, the Delle Pulci market.
Delle Pulci market is open all week from 9 to 19:30, in the winter closed on Sundays and Mondays.
About once a month, on Sunday, the flea market turns to antique market where you can buy such old antique things as coins, books, jewelry, paintings, porcelain and a lot of other curious things.

Other Sunday markets arethe ones at Piazza Santo Spirito and Giardino della Fortezza.

Loggia del Pesce

The Loggia del Pesce, a historical building in Florence, is formed by nine wide arcades, supported by piers or columns. On each side are eight medallions depicting fishing activities and the sea. At the corners are four coats of arms.

It was commissioned by Duke Cosimo I de' Medici to Giorgio Vasari, to house the fish market which had been previously held near the Ponte Vecchio. Their place there was taken by the Vasari Corridor.

During the urban renovation of Florence following the unification of Italy (1885–1895), the loggia was dismantled and most of its decoration went to the museum of San Marco. It was rebuilt in the Piazza Ciompi only in 1956, re-using most of the original materials.[1]

Bar Plaz, on via Pietrapiana 36r, just across from the loggia, is a good spot to enjoy the atmosphere of the square. For lunch we recommend Teatro del Sale, a restaurant set up in an old theater, or Cibrèo trattoria (called il Cibrèino), run by Fabio Picchi.
