This building is a Roman Catholic cathedral, dedicated to S. Maria Assunta, under the designation Santa Maria Matricolare. It is the episcopal seat of the Diocese of Verona.
It was erected after two Palaeo-Christian churches on the same site had been destroyed by an earthquake in 1117.
Built in Romanesque style, the cathedral was consecrated on September 13, 1187.
The structure was later modified by several renovation interventions, although the plan has remained unchanged.
It is the central structure of a complex of architectural buildings which include S. Giovanni in Fonte, S. Elena, the Canons’ cloister, the Capitular library, the square in front of the church and the bishop’s residence.
Address: Piazza Vescovado.
