From the old 11th century priory to Nerbis, in the Landes, only a cemetery gate and Saint-Pierre church remain today. Listed as Historical Monuments, the latter was erected in the 10th century, experiencing many troubles over the centuries, even seeing its monastery burnt down during the Hundred Years War in the 15th century.
Modest in size, the Saint-Pierre church in Nerbis is a fine example of Romanesque architecture, revealing in particular thirty-five keystones similar to those of Bordeaux cathedral. The building is in the form of a nave and a south aisle opening onto a transept which leads to an apse with three apses. It has retained from its origins the chevet or the two vaulted apses in cul-de-four, but has undergone many transformations over time. With a fortified bell tower in the 14th century, the church also underwent an expansion in the 16th century by the addition of a collateral.
