The church is one of the best examples of Romanesque architecture. It is known for its campanile and for its murals, which were removed to the MNAC (National Art Museum of Catalonia) (Barcelona) in 1922, to prevent the theft of the murals. The murals, which are frescos, were removed by painting them with horsehide glue and then peeling off the hardened glue, carrying the pigments of the mural with it.
Among the murals is a striking rendition of Christ Pantocrator. In His left hand He holds a book which reads "EGO SUM LUX MUNDI", "I am the light of the world". On His right and left are the Greek letters alpha and omega.
