The Vasari Corridor (Corridoio Vasariano), designed by Giorgio Vasari in the 16th century, is an elevated medieval passageway connecting Palazzo Vecchio and the Pitti Palace (Palazzo Pitti), each set on opposite banks of the Arno River in Florence. Snaking through and along many of the city's landmarks, the near-mile-long, elevated walkway was once a secret, used by the Medici family to travel unnoticed through Florence. Today, it is an art gallery, home to Italy’s most important collection of self-portraits. Visitors can admire views over the river from its large windows running over the Ponte Vecchio.
