A “must-see” list for Florence usually includes checking out Renaissance art at the Uffizi Gallery, having a quick look at Michelangelo’s David, and taking a walk to admire the incredible feat of architecture of the Florentine Duomo. However, there are many other less obvious art history treats in Florence. One of them, in place since the mid-17th century but closed for renovations for the last eight years, is the celebrated Vasari Corridor—the secret Medici passage high above the city streets. The corridor reopened to the public a few months ago, and I was happy to check it out.
