This is one of the most important Romanesque buildings in Europe and a World Heritage Site. Construction started in 1099 under the direction of architect Lanfranco, where the tomb of St. Geminianus is, the patron saint of Modena. Since the V century, two churches were built in the same place, but both had been destroyed. The saint's remains are still exhibited in the crypt of the majestic cathedral. The rosette was added by Anselmo in the 13th century, while the two lions supporting the columns of the entrance are from ancient Roman times, and were probably discovered during excavation to lay the foundation. Inside, the cathedral is divided into three naves. Between the nave and the crypt is marble parapet by Anselmo da Campione representing the Passion of Christ and the Last Supper. The pulpit was designed by Arrigo da Campione, and is decorated with terracotta figurines. Another interesting piece is the wooden crucifix from the XIV century.
Near the Palazzo del Comune is the Duomo or cathedral dedicated to San Giorgio - according to a now lost inscription the church was built by Guglielmo degli Adelardi I (died 1146), ve is buried in it. The sculpture of the main portal is the work of the artifex Nicholaus, mentioned in the lost inscription as the architect of the church. The top of the main façade, with arcades of pointed arches, dates from the thirteenth century and the portal had lions lying and elaborate sculptures above. The interior was restored in Baroque style in 1712, because of a disastrous earthquake in 1570 that destroyed not only the interior of the cathedral, but also numerous buildings throughout the city. After this restoration the Porta dei Mesi was closed at the imposing entrance on the south side. The campanile, in the Renaissance style, dates from 1451-1493, but the top floor was added in the late sixteenth century. It is one of the prettiest squares in the country with a palace, cathedral, castle and street stalls that make wandering around this part of the town an absolute delight. Beautiful!
