Cwmhir Abbey

Cwmhir Abbey is a Cistercian monastery ruin in Wales with remains dating to the medieval period. The stone fragments show parts of the original church nave, located on a slope at about 250 meters elevation.

The abbey was founded in 1176 and suffered multiple attacks from English soldiers during the 13th century. These repeated conflicts caused significant damage to the buildings and shaped the site's story.

The place holds deep ties to Llywelyn ap Gruffudd, the last native Prince of Wales, whose remains were laid to rest here after his death. This connection makes the ruins a meaningful landmark in Welsh identity and memory.

Access is via farm roads connecting Abbeycwmhir to Crossgates, with parking available near the site. The ground is rough and uneven, so wear appropriate footwear when exploring the ruins.

The original building plans envisioned a structure the size of a cathedral, but only the nave was completed. Political instability of the time prevented the ambitious design from being finished.
