Site Description
NAR SH93NW1
An oval earthwork enclosure generally identified as a medieval castle. It is defined by a massive rampart, up to 5.2m high, with traces of an external ditch. The area enclosed is only about 26m north-south by 18m. The whole area may have been raised or else a natural knoll was utilised.
The enclosure has been mutilated on the south.
This is the only castle site known within Penllyn Istreweryn commote. The customs and tolls of the market and fair of Llanfor (?Llanfawr) were transfered to the new foundation of Bala in 1310-11.
