The Palazzo Vecchio ( "Old Palace") is the town hall of Florence, Italy. It overlooks the Piazza della Signoria, which holds a copy of Michelangelo's David statue, and the gallery of statues in the adjacent Loggia dei Lanzi. Originally called the Palazzo della Signoria, after the Signoria of Florence, the ruling body of the Republic of Florence, this building was also known by several other names: Palazzo del Popolo, Palazzo dei Priori, and Palazzo Ducale, in accordance with the varying use of the palace during its long history. The building acquired its current name when the Medici duke's residence was moved across the Arno River to the Palazzo Pitti. History In 1299, the commune and people of Florence decided to build a palace that would be worthy of the city's importance, and that would be more secure and defensible in times of turbulence for the magistrates of the commune. Arnolfo di Cambio, the architect of the Duomo and the Santa Croce church, began construction upon the ruins of Palazzo dei Fanti and Palazzo dell'Esecutore di Giustizia, once owned by the Uberti family. Giovanni Villani (1276–1348) wrote in his Nuova Cronica that the Uberti were "rebels of Florence and Ghibellines", stating that the palazzo was built to ensure that the Uberti family homes would never be rebuilt on the same location. The cubical building is made of solid rusticated stonework, with two rows of two-lighted Gothic windows, each with a trefoil arch. In the 15th century, Michelozzo di Bartolomeo Michelozzi added decorative bas-reliefs of the cross and the Florentine lily in the spandrels between the trefoils. The building is crowned with projecting crenellated battlement, supported by small arches and corbels. Under the arches are a repeated series of nine painted coats of arms of the Florentine republic. Some of these arches can be used as embrasures (spiombati) for dropping heated liquids or rocks on invaders. The solid, massive building is enhanced by the simple tower with its clock. Giovanni Villani wrote that Arnolfo di Cambio incorporated the ancient tower of the Foraboschi family (the tower then known as "La Vacca" or "The Cow") into the new tower's facade as its substructure; this is why the rectangular tower (height 94 m) is not directly centered in the building. This tower contains two small cells, that, at different times, imprisoned Cosimo de' Medici (the Elder) (1435) and Girolamo Savonarola (1498). The tower is
