Discover Pisa's Cathedral Square, better known as the Miracles Square (Piazza dei Miracoli) and formed by a unique ensemble of four monumental buildings (aside from the tower, there is the Cathedral, the Baptistery and the Monumental Cemetery) as well as by two matchless collections – the Museum of Sinopie and the Museum of the Opera. All the monumental buildings are closely related, and ruled by a single design concept.
