Dinefwr Castle, Medieval castle in Llandeilo, Wales.
Located within Dinefwr Park National Nature Reserve, the castle ruins stand atop a hill overlooking 800 acres of rolling countryside and ancient woodlands.
The castle served as the primary stronghold of the Kingdom of Deheubarth from the 9th century and was established by Rhodri the Great as a defensive structure.
The castle remains demonstrate traditional Welsh military architecture with its circular towers, defensive walls, and strategic positioning above the Tywi Valley.
Access to Dinefwr Castle requires a moderate uphill walk through Castle Woods, with guided tours available from March through November during daylight hours.
Two Roman forts were discovered beneath the castle grounds through ground radar surveys in 2003, revealing military occupation from the first century AD.
