Castle of Montllor Monument · Gavet de la Conca, Pallars Jussà, Lleida Also called the castell de l'Hostal Roig or dels Moros, it defended the pass through the Noguera valley; only a stretch of circular tower survives, about 2 m in diameter and 2.5 m at maximum height, built of medium rubble masonry with reddish lime mortar, along with a partly natural ditch and sockets cut into the rock for the outer walls. It is first documented in 1247, in connection with the path that the monks of the priory of Meià built that century to link up the area, but given its building technique — courses of medium ashlar bound with reddish mortar — it must have been raised around the year 1000, much earlier. Linked to the vanished monastery of Sant Privat, it stands about 100 m above L'Hostal Roig. Cultural Asset of National Interest. Photo: Ilerda (CC BY-SA 3.0) What to see and do in Gavet de la Conca
