This octogonal building in front of the Duomo is one of
Florence's oldest buildings. We were there in May and permanently there was a
huge line in front of the building. I though I will leave Florence without
seeing it. In the last day I tried again, arriving in the Piazza del Duomo
about 15 minutes before the closing time. This time there were only a few
people in line so I bought a ticket. It was really worth it, the 13th century
mosaics which illustrated the Last Judgement are so beautiful. I stayed there
until closing time.
