The much loved Square of Miracles or 'Campo dei Miracoli' is Pisa's main attraction due to the presence of its famous Leaning Tower or Campanile. This Unesco World Heritage Site also contains the cathedral or Duomo, the Baptistry, the Camposanto Monumentale Cemetery, as well as the New Hospital of the Holy Spirit with the Sinopias Museum. They are all built in an Early Renaisance Italian style which revolutionized Italy and the world.
