|Piazza dei Miracoli gathers all the monuments that make it so famous: Duomo, Baptistery, the Leaning Tower, Camposanto (cemetery), Museo della Sinopie and Museo dell' Opera del Duomo. The building of this masterpiece of Romanesque-Pisan art started in 1063 by Buscheto. Pisa's cathedral was the first building to use the horizontal marble stripe motif. The work on the Cathedral was finished two centuries later by Rainaldo. Among the highlights of the museum is an imposing 10th century hippogriff, (half horse, half griffin) cast in bronze by Moorish craftsmen.
