Castle of Lillet Monument · la Pobla de Lillet, Berguedà, Barcelona The castle of la Pobla de Lillet is the surviving part of the fortification that the lords of Mataplana built in 1293, on the hill where the rivers Llobregat, Aritja and Regatell meet, within the broad and fertile valley of Lillet. Ramon II d'Urtx, lord of Mataplana, and his son Hug de Mataplana granted a founding charter to la Pobla de Lillet on 15 April 1297, and the fortress was built beside it to defend the whole barony and shelter its inhabitants from possible invaders. The building containing the entrance gate was altered in its southern half in the 18th century, when the church of Santa Maria de Lillet was enlarged, while the northern half was restored in 2007. It currently operates as tourist accommodation with a spa area. Photo: Enfo (CC BY-SA 3.0) What to see and do in la Pobla de Lillet
