The Uffizi Gallery (or Galleria degli Uffizi), is one of the oldest and most celebrated art museums in the world. It is located in the Palazzo degli Uffizi, in Florence, Italy - the home of the European Renaissance. As one might expect from the foremost museum of the Florence Renaissance, its collection of masterpieces from the Proto, Early and High Renaissance eras, initiated by the powerful Medici family, later enlarged by the Lorraine Grand Dukes and completed by the Italian State authorities, is second to none. It also includes other important collections, notably the Contini Bonacossi Collection and the Collection of Prints and Drawings (Gabinetto Disegni e Stampe degli Uffizi). The Uffizi has been open to visitors since the late 16th century, and was officially opened to the public in 1765.
