Dryslwyn Castle

Dryslwyn Castle is a medieval fortress sitting on an isolated hill in the Tywi Valley in Wales. The stone remains include three distinct sections with defensive walls and structures that date from the 13th century.

The castle was built in the 13th century as a Welsh stronghold and fell in 1287 after a three-week assault using siege weapons. This event marked the end of Welsh independence in the region under English control.

The castle reflects how Welsh lords once built their own stone fortifications to protect their lands and assert power. Walking through its remains shows the importance this stronghold held for the kingdom of Deheubarth.

The site is easy to reach with parking available near the entrance for visitors. The open ruins can be explored in different light throughout the day, so visiting in early morning or late afternoon often provides better views and photo opportunities.

Archaeological digs have uncovered massive stone projectiles that were fired from siege weapons during the attack. These surprising finds give visitors a direct sense of how fierce the fighting was to take the fortress.
