The Church of Sant Martí de Pau was built in Romanesque times. In the first phase, in the 11th century, the semicircular apse and part of the single nave were built, made of small pebbles.
The rest of the nave and the façade correspond to a second phase, between the end of the 12th and the beginning of the 13th, and were built with well-worked granite ashlars.
The cover has five graduated semicircular arches ending in two columns on either side of the door. On the columns, capitals that combine plant decorations with animal and monster shapes. Some members of the Pau family chose to be buried inside the church, as some 14th century tombstones we find inside remind us.
Over the centuries, the church has been reformed; the sacristy and a chapel dedicated to the Virgin of the Roser were added, among other modifications. Furniture, altarpieces and other ancient liturgical objects were lost during the first days of the Civil War, in 1936.
