Dinefwr Castle and Park ( Newtown House)

Dinefwr Castle and Park ( Newtown House)


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.
