Piazza del Duomo, Pisa

The Piazza dei Miracoli, formally known as Piazza del Duomo, is a walled 8.87-hectare (21.9-acre) compound in central Pisa, Tuscany, Italy, recognized as an important center of European medieval art and one of the finest architectural complexes in the world. It was all owned by the Catholic Church and is dominated by four great religious edifices: Pisa Cathedral, the Pisa Baptistery, the Leaning Tower of Pisa, and the Camposanto Monumentale. Partly paved and partly grassed, the Piazza dei Miracoli is also the site of the Ospedale Nuovo di Santo Spirito, which now houses the Sinopias Museum and the Cathedral Museum.
