Yesterday, we entered the cathedral for free. The black and white marble inlaid floor was covered and the church was filled with flags of the contradas. The Cathedral was open to all because of the Palio. Today we paid cash to get inside again the floors were exposed and the flags were removed. The church, both days, was packed with a few hundred people but there was still space for everyone because it is so massive. It truly is an incredible interior and we managed to catch a few Michelangelo sculptures.
