The Corridoio Vasariano is an elevated enclosed passageway in Florence which connects the Palazzo Vecchio with the Palazzo Pitti. The Corridor was built in 5 months by order of Grand Duke Cosimo I de' Medici in 1564, to the design of Giorgio Vasari. It was commissioned in connection with the marriage of Cosimo's son, Francesco, with Johanna of Austria. The idea of an enclosed passageway was motivated by the Grand Duke's desire to move freely between his residence and the government palace, when, like most monarchs of the period, he felt insecure in public. The meat and fish market of Ponte Vecchio was moved to avoid its smell reaching into the passage, its place being taken by the goldsmith shops that still occupy the bridge.
The passageway now contains over 1000 paintings, all dating from the 17th and 18th centuries, as well as the important collection of Self-portraits by some of the most famous masters of painting of the 16th to the 20th century.
