Dryslwyn Castle
Dryslwyn Castle is a native Welsh hilltop castle sited on a steep limestone knoll above the Towy Valley in Carmarthenshire. Built in the early 13th century and expanded in the later 13th century, it retained a polygonal inner ward with a round keep and multiple concentric wards. Much of the masonry was deliberately slighted in the early 15th century and today the site survives as extensive ruins.

As it stood in 1290
The shape it held in its prime.
Perched on a steep, grass-covered limestone hill, Dryslwyn's plan in its prime was a polygonal inner ward whose curtain wall closely followed the hilltop contours. A round keep with a flared base occupied the south side and a remodelled gatehouse lay to the north‑east approach. The stone curtain walls enclosed roofed ranges including a great hall and an adjoining service range interpreted as a kitchen; traces of middle and outer wards extended to the north‑east of the summit.
Its story
The story of Dryslwyn Castle.
Dryslwyn was built in about the 1220s by one of the princes of the kingdom of Deheubarth, on a rocky hill overlooking the Towy Valley roughly halfway between Llandeilo and Carmarthen. It is considered one of the most important surviving structures built by a Welsh prince, and is noteworthy as the only native Welsh castle to have had three wards.
After the death of Dafydd ap Gruffudd, the last native prince of Wales, in 1283, Dryslwyn was one of the few substantial stone castles in Wales still held by a Welshman. Rhys ap Maredudd, the most prominent surviving Welsh lord, continued to augment its defences — the English allowed him to keep his castle because he had shown a more conciliatory attitude towards them than other Welsh lords.
The castle changed hands several times in the struggles between Welsh and English before being systematically demolished in the early fifteenth century, presumably to stop Welsh rebels using it again. The polygonal inner ward holds the principal remains, including the Round Tower — the original keep — a remodelled gatehouse surviving at foundation level, and the foundations of the great hall and of Rhys ap Maredudd's hall. It is a Grade I listed building.
