One of the oldest sites in Florence, the Baptistery of St. John, which stands in front of the Cathedral. I have mentioned before, that I could not get over the amount of tourists that were there in October 2016. I have never seen so many people, not even in London. We did not want to spend hours queuing for St John and the Cathedral, there was so much more to do in one day, so I made do with some exterior shots, trying to miss the bodies.
I found a photo of the wonderful roof and I think that would be worth a return visit. The origins of St John are unknown, although it is believed that it was built over the ruins of a Roman temple dedicated to Mars dating back to the 4th-5th century A.D. It was first described in 897 as a minor basilica. In 1128, it was consacrated as the Baptistery of Florence and as such is the oldest religious monument in Florence.
