12th-century Welsh castle, historic house and 18th-century landscape park, enclosing a medieval deer park
A magical land of power and influence for more than 2,000 years, Dinefwr Park and Castle is an iconic place in the history of Wales. Two forts are evidence of a dominant Roman presence. The powerful Lord Rhys held court at Dinefwr and influenced decisions in Wales.
The visionaries, George and Cecil Rice designed the superb 18th-century landscape that you see today.
The 'hands-on' Newton House gives visitors an atmospheric circa 1912 experience. Exhibitions on the first floor tell Dinefwr's story and inspire visitors to explore the castle and park.
We have made some slight changes to our opening in 2014, so please make sure you check our website before planning your visit. Despite the changes, work never stops at Dinefwr. Our staff and volunteers are working hard behind the scenes to deliver new visitor projects, conservation work and of course taking care of our ancient breed of White Park Cattle.
Hidden House Tours
If your visiting Newton House, a guided Hidden House tour of our 17th-century mansion is a must. You can go behind the scenes to places not usually available to public view. Hear all the upstairs-downstairs gossip and can enjoy some breathtaking views from the roof.
