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've a full list of events running throughout the year at Dinefwr and this autumn has something for everyone.
Join us for some half term pumpkin carving or take in the dazzling display of colour in the ancient woodland. Don't forget to listen out for the sounds of clashing antlers, we're in the middle of the fallow deer rut.
Why not take a tour of Newton House, one of the National Trust' most haunted houses? Many spooky stories about spirits and scandal surround this old house, so come along and experience it for yourself.
Brand new art gallery
We've opened a new area of Newton House that was previously closed to visitors and thought it was the perfect place for an art gallery. We've a different exhibition on every month from some of the best artists in the country. Check out our events page for our listings.
Hidden house tours
If you're 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 enjoy some breathtaking views from the roof.
