Walls of Bagà Monument · Bagà, Berguedà, Barcelona Medieval walled enclosure of the old town of Bagà, in the Berguedà, declared a Bien Cultural de Interés Nacional (Catalonia's highest level of heritage protection). Its layout is preserved, along with the Portella tower, remains of the Portalet tower and the Vilella tower, several stretches of wall in Muralla and Portalet streets, and two arrow slits in the houses of Muralla street. It is an austere work of undressed ashlar laid in courses and bound with mortar, built on a slope beside the river Bastareny. The founding charter was granted in 1233 by Pere Galceran de Pinós, and the fortification is documented as early as 1289 and again in 1335; by the 19th century only remains of the walls were left.
