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 Christmas is an extra special time, especially for Newton House.
Our volunteers are dressing the house as it would've been in the Edwardian times, with greenery from the estate and hand-crafted decorations for the tree.
Will you be joining us on the 29 & 30 November as we celebrate the true values of Christmas at the Llandeilo Edwardian Christmas Fayre at Dinefwr? The whole of Newton House will be packed with craft and food stalls, Santa will be in his grotto, choirs will be singing and there's free mulled wine and mince pies for everyone. Free Parking
If you don't find what you want here, why not take a trip in the nearby town of Llandeilo?
Christmas arrivals in our shop
Our brand new shop is unlike any other National Trust shop. We support local and independent business and stock our shelves with what we know our customers love. You're guaranteed to find something for everyone, from Welsh woollen blankets to beers and whiskeys.
In fact, our shop has been so popular, we're opening a special pop-up shop in the local town of Llandeilo for the Christmas period.
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.
Go to the Visitor Centre on arrival or call on 01558 824512 to book your place.
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.
Wonderful wedding venue
Get married in a land steeped in Welsh history and tradition. Newton House is nestled within an 800-acre countryside estate and can cater for ceremonies and civil services of up to 90 guests.
