The village, declared a historical-artistic and cultural centre of national interest, is one of the most important villages of Catalonia in terms of medieval architecture. With extraordinary appeal and beauty, it preserves its ancient feudal appearance, with narrow and tortuous streets and numerous entrances and alleyways. The route through the town allows you to discover different points of view of the castle-palace and the walls and various popular architecture. The whole town is located on sandstone rock, worked in various ways. There is no doubt that the most impressive elements are the wall valleys, with trenches excavated into the live rock.
