According to Brut y Tywysogion (Chronicle of the Princes), Cymer Abbey was founded in 1198. It was a Cistercian Abbey and the only monastery established in Meirionnydd. The remote locations of Cistercian monasteries reflected the strict restrictions on monks pursuing their learning in the middle ages.

It is believed that Cymer Abbey was founded under the patronage of two brothers, Gruffudd and Maredudd ap Cynan, grandsons of Owain Gwynedd. The relationship between European monasteries and important ruling families was close.

Cymer Abbey used areas of Gwynedd and Powys for grazing cattle and would breed horses.

Hiking

Interesting ruins to explore, though not as extensive or atmospheric as Castell y Bere, for example. Worth a visit though.
