The castle was built by the Normans in the 11th century as part of a line of defences constructed along the Marches to repel Welsh invasions. It is a romantic ruin with evidence of the changes made by each resident throughout its history. It has been owned by the Earls of Powis since 1811. The castle is open 7 days a week from Mid February to December but closed on Christmas Day. From January to mid February it is only open on weekends. The castle is subject to weather conditions and we reserve the right to close the castle if we deem it unsafe for visitors due to inclement weather. During the Festival build ups there are closed days for your safety. Information can be found on our website and at the Tourist Information Centre. Access to the Gift shop and Traditional Tea Rooms is free.
