The Loggia dei Lanzi, also called the Loggia della Signoria, is a building on a corner of the Piazza della Signoria in Florence, Italy, adjoining the Uffizi Gallery. It consists of wide arches open to the street. The arches rest on clustered pilasters with Corinthian capitals. The wide arches appealed so much to the Florentines that Michelangelo proposed that they should be continued all around the Piazza della Signoria.
Sometimes erroneously referred to as Loggia dell' Orcagna because it was once thought to be designed by that artist, it was built between 1376 and 1382 by Benci di Cione and Simone di Francesco Talenti, possibly following a design by Jacopo di Sione, to house the assemblies of the people and hold public ceremonies, such as the swearing into office of the Gonfaloniers and the Priors. Simone Talenti is also well-known from his contributions to the churches Orsanmichele and San Carlo.
The vivacious construction of the Loggia is in stark contrast with the severe architecture of the Palazzo Vecchio. It is effectively an open-air sculpture gallery of antique and Renaissance art.
