The Piazza dei Miracoli, also known as the Piazza del Duomo, is a walled area in Pisa, Tuscany, Italy, renowned for its exquisite medieval art and as one of the world's most impressive architectural complexes. This UNESCO World Heritage Site is home to four great religious edifices: the Pisa Cathedral, the Pisa Baptistery, the iconic Leaning Tower of Pisa, and the Camposanto Monumentale. The square's name, which translates to 'Square of Miracles,' was inspired by the Italian writer Gabriele D'Annunzio, reflecting the sheer wonder and historical significance of this site.
