Castle of Guàrdia Monument · Castell de Mur, Pallars Jussà, Lleida Castle from the late 11th or early 12th century with an original triangular tower with rounded corners; the eastern stretch of wall survives (24 m long and 3 m high, with five arrow slits) along with the tower, about 8 m high with door openings and remains of battlements. It belonged to the counts of Pallars, passed to the Mur family, and in 1381 to Berenguer d'Abella; it visually controlled the Terradets gorge together with the castle of Mur.
