In addition to visiting museums and the Dome in Florence I also visited the Palazzo Pitti and it's 11 acres of gardens. The gardens were beautiful but I haven't been out of an urban setting in weeks so probably anything would have seemed nice to me. The center of the garden, built for the Medici family in 1550, is one of the best examples of 16th century Italian gardens and rightfully so. The heart of the garden is a large Roman amphitheater located near the palace with a reflecting pool dedicated to Neptune behind it.
I wandered around the gardens for hours discovering fun architectural follies, hedge mazes, sculptured flower beds, and even a garden villa overlooking the Tuscan countryside. The views were amazing from the top of the garden. We could see the setting sun to the west and the entire city of Florence to the east behind the Palazzo. It was a great stop on the trip since I got a chance to draw some quick sketches of fountains, and take a brief break from city life.
