The Uffizi Gallery is a prominent art museum located adjacent to the Piazza della Signoria in the Historic Centre of Florence in the region of Tuscany, Italy. One of the most important Italian museums and the most visited, it is also one of the largest and best known in the world and holds a collection of priceless works, particularly from the period of the Italian Renaissance.
After the ruling House of Medici died out, their art collections were given to the city of Florence under the famous Patto di famiglia negotiated by Anna Maria Luisa, the last Medici heiress. The Uffizi is one of the first modern museums. The gallery had been open to visitors by request since the sixteenth century, and in 1765 it was officially opened to the public, formally becoming a museum in 1865.
The building of the Uffizi complex was begun by Giorgio Vasari in 1560 for Cosimo I de' Medici so as to accommodate the offices of the Florentine magistrates, hence the name uffizi, "offices". The construction was later continued by Alfonso Parigi and Bernardo Buontalenti; it was completed in 1581. The top floor was made into a gallery for the family and their guests and included their collection of Roman sculptures.
