Dinefwr is an iconic place in the history of Wales. Two forts are evidence of a dominant Roman presence, through the to the Medieval times when the Princes of Deheubarth held Dinefwr Castle as a seat of power and influence. In the 19th Century George and Cecil Rice created the designed landscape the park displays today, clearly inspire by Capability Brown who visited in 1773. The parkland hosts many walks through Bog Wood, the Medieval Deer Park and alongside the majestic White Park Cattle who have roamed the lands at Dinefwr for over 2,000 years. There are plenty of activities, tours and events held throughout the year. Newton House is not a traditionally “dressed” house, more a hands on atmospheric experience telling the stories of the families that shaped this 800 acre estate. Dinefwr is the first parkland National Nature Reserve in Wales with beautiful woods, lakes and parkland to explore. Dinefwr Castle is owned by the Wildlife Trust and Managed by Cadw.
