The mine workings extended out under the sea. The pumping engine house that survives at the cliff edge - granite walls, narrow chimney, a roof gone to sky - was built in 1872 to fight what the miners called the great enemy: water. It is one of the most photographed industrial ruins in Britain, the kind of place where Cornwall stops looking like a county and starts looking like a parable about labour and weather. Wheal coates means simply 'Coates Mine' in Cornish-English mining argot. The men who worked it called it home.

Wheal Coates: Tin Beneath the Ocean

Without it the seawater would have won. The Towanroath shaft drops 600 feet through Devonian slate to follow a tin lode that runs out beneath the Atlantic, and fr...

Wheal Coates: Three Engine Houses and a Calciner

Sat, 23 May 2026 00:00:00 GMT

Photo credit Tony Atkin, CC BY-SA 2.0. Three engine houses still stand at Wheal Coates, and each one did a different job. The Towanroath Pumping Engine House, perched at the very edge of the cliff, contained a Cornish engine whose beam rocked night and day to keep the shaft below it dry. A short walk uphill, the Old W...

Wheal Coates: The Cliff That Will Win

Sat, 23 May 2026 00:00:00 GMT

Photo credit Martinvl, CC BY-SA 4.0. Cornwall's north coast is winning a slow argument with everything humans have ever built on it. The cliffs at St Agnes are erosional - they retreat a little each century under storms that arrive directly off the Atlantic with three thousand miles of open water behind them. The To...

Wheal Coates: What You Hear

Sat, 23 May 2026 00:00:00 GMT

Photo credit Trevor Rickard, CC BY-SA 2.0. Wheal Coates is quiet now, but the quiet has a particular Cornish texture. Wind comes up the cliff and through the missing roof, and on a wild day the engine house breathes like a flue. Choughs - the red-legged, red-beaked Cornish crow that vanished from the county for fifty year...
