The Uffizi Gallery (Italian: Galleria degli Uffizi, Italian pronunciation: [ˌɡalleˈria deʎʎi ufˈfittsi]) , is a museum in Florence, Italy. It is one of the oldest and most famous art museums of the Western world.

Building of the palace was begun by Giorgio Vasari in 1560 for Cosimo I de' Medici as the offices for the Florentine magistrates — hence the name "uffizi" ("offices"). Construction was continued to Vasari's design by Alfonso Parigi and Bernardo Buontalenti and ended in 1581. The cortile (internal courtyard) is so long and narrow, and open to the Arno River at its far end through a Doric screen that articulates the space without blocking it, that architectural historians treat it as the first regularized streetscape of Europe. Vasari, a painter as well as architect, emphasized the perspective length by the matching facades' continuous roof cornices, and unbroken cornices between storeys and the three continuous steps on which the palace-fronts stand. The niches in the piers that alternate with columns were filled with sculptures of famous artists in the 19th century.
