Castle of Toralla Monument · Conca de Dalt, Pallars Jussà, Lleida Romanesque frontier castle documented in the 9th-10th centuries with notable activity in the 11th; it preserves a circular tower built directly on the rock, about 8 m in diameter and up to 5 m high, and a stretch of wall of irregular, unworked large stones, today covered in vegetation. In 1057 Count Artau I of Pallars Sobirà included it in his wife's dowry to the counts of Barcelona; a local lineage held it from the 12th century until in 1645 it passed by marriage to a baron of Sentmenat.
