This church (from the end of the 10C), in Lombard Romanesque style, was built in a cruciform shape. The façade is decorated with blind arcades held up by carved supports. Some Visigothic elements are still visible here. The interior, with a single nave and barrel vault, is of restrained proportions. The small cloister (11C-12C), with its gallery of trefoil arches and its twin columns, is one of the most pleasant places of all.
