Most of Catalonia’s important artistic heritage originated in the Middle Ages. Romanesque art developed with the establishment and development of Catalonia and the formation of the Catalan language, and was strongly influenced by the Lombard style. Lombard art originated in the Pyrenees valley. Catalonia still retains more than 2,000 Lombard-style buildings. Among them, the Roman church in Boyi Valley is the most famous, listed as a World Cultural Heritage Site by UNESCO, St. Pied Rhodes Monastery and Zuder Cathedral. However, the most symbolic and monumental are the pictures and sculptures in the Museum of Catalonia (MNOC). The Catalan Museum is one of the most important collections of Roman and Gothic art in the world and in the bishopric.
