Gelli-groes Mill, Grade II* listed watermill in Pontllanfraith, Wales
The water-powered corn mill features an overshot wheel with cast iron frame and wooden buckets designed for grinding barley and wheat.
Built around 1625, Gelli-groes Mill operated commercially until the 1980s, making it the final working mill in Monmouthshire.
The mill house gained recognition when resident Artie Moore received radio transmissions from the Titanic in 1912 using his self-built wireless receiver.
The mill adapted to changing times by installing electrical generators in the 1900s, providing battery charging services for local farmers before mains power arrived.
Royal candlemaker David Constable occupied the mill from 2000, maintaining the historical machinery while bringing new purpose to the structure.
