Castle of Montclús Monument · Sant Esteve de Palautordera, Vallès Oriental, Barcelona The frontier castle of Montclús was the centre of the important barony of the same name, on the foothills of the Montseny, above the plain of Palautordera. Its origin lies between the 11th and 12th centuries, although it did not gain importance until the 13th, when the lords of Sesagudes abandoned the castle of the Montseny to settle here, with jurisdiction over a good part of the neighbouring parishes. In the 14th century it was transformed into a palace, and in 1403 its dependence on the Hospital of Sant Celoni ended when the barony passed to Bernardino de Cabrera, whose descendants still held it in the mid-15th century. The complex preserves two phases: a circular tower with an adjoining hall, built in opus spicatum masonry datable to the 10th century, and an almost square-plan walled enclosure from the late Middle Ages.
