Fortified Enclosure of Cervera Monument · Cervera, Segarra, Lleida The fortified precinct of Cervera is the town wall, declared a Bien Cultural de Interés Nacional (Catalonia's highest level of heritage protection), developed from the castle on the hill of Montseré, to the southwest of the present urban centre. The walls and defensive towers were built in the 14th century, making use of an earlier fortification already mentioned in the 11th century. In 1285 King Peter II ordered walls to be raised and ditches dug in the face of the threat of a French invasion, and the conversion of the town into a fortress was completed in the mid-14th century under Peter III, in the face of the conflict with Castile. Its walls were bombarded for the first time in the siege of 1463-1465 by the troops of John II, and in 1706 those of Archduke Charles of Austria forced their height to be lowered, in reprisal for the support given to Philip V.
