In the 13th century a nave was added to the Romanesque apse and surmounted by a wall-belfry above the apse. Flanked to the north by a cemetary onto which opened the 'Gate of the Dead'. (covered by a porch), it played a defensive role on it's south side. The nave was restored and the belfry was erected in 1520; the apse was topped with defences a few decades later.
