Visit to Coed Trewernau Mill, Abbeycwmhir


Sunday, July 2, 2023

Coed Trewernau Mill is an extant corn mill on the bank of the Clywedog Brook, near Abbeycwmhir in Radnorshire. It is a very small corn mill with wooden working parts – doubtless once typical of many rural mills in Wales. It must have served a very small and scattered population, probably ceasing work over a hundred years ago.

Coed Trewernau has origins as least as far back as 17th century when it was owned by the Hanmer family of Llanddewi Hall. A wealthy tanner from Presteigne owned the mill in the late 18th century, and later the mill was acquired by the Glanusk Estate. 

The working parts, shown in the photo, are a rare survival of rural mid to late 18th century millwrighting.
