The Castell Mynach

The Castell Mynach pub sits alongside of the A4119 a short distance from the village of Groesfaen.

Built in the 1930’s, the name Castell Mynach translates into English as: “The Castle of the Monks”, and refers to what is locally considered to be an old monastery which the pub overlooked.

This was probably a monastic building rather than a monastery and the ruins still stand in the fields across the A4119 dual carriageway. Potentially dedicated to St Cawdraf it was demonstrated by the Royal Commission on Ancient and Historic Monuments of Wales in 1982 to be a medieval courtyard house.

The pub was originally a residence which is much older and the pub was extended to accommodate the hostelry and the pub restaurant now stands on the grounds of the old stables.

South of the pub in the fields on the east of the dual carriageway near to College House stood Llangoed Chapel. This has largely disappeared now but was standing back in the 14th Century as it was shown on local maps of that date.
