St Trillo
Llandrillo yn Rhos, Clwyd
Mae’r adeilad syml, to carreg, bach iawn hwn, yn wyth troedfedd o uchder ac un droedfedd ar ddeg o hyd; mae ei waliau o drwch dwy droedfedd ac o dan ei allor, mae ffynnon sanctaidd St Trillo.
This is not the first time this Cistercian monastery, founded in 1150 by David I of Scotland, has suffered.
In more turbulent times it was caught in the Anglo Scottish wars of the 14th century. But a good bit of luck followed the Dissolution of the Monasteries, when the local people successfully petitioned Thomas Cromwell to allow them to continue to use the church, partially as a refuge and defence against the Scots.
The rest of the abbey, however, fell into disrepair; bumps in the nearby field indicate the precinct remains, and regular archaeological excavations uncover fragments from the abbey's past.
