This magnificent Romanesque church has an austere façade dating from the 10 and 11C, its warm colours and mighty walls relieved by Lombard bands. Above the narthex, St Michael's Chapel has capitals dating from the Carolinian period. The bareness of the nave, bathed in a soft pink light is striking. The rest of the church as built in the 12C and is white in colour. The crypt was built in the 10C.
