I first visited Italy as a backpacker in 1978. The pictures below were taken when I returned in 2007 to visit my daughter who was doing a semester abroad in Florence.
I was struck by how different the Duomo appeared after not seeing it for 30 years. We climbed 414 steps to the top of the Campanile for outstanding views of the entire area. The Boboli Gardens at the Piti Palace of the Medici's remains a personal favorite.
