Why it's Wildland
7.8Built as part of the Elan Valley Water Scheme, Caban Coch is a 37-metre-high dam designed to look like a waterfall when water spills over its crest.
This is industrial infrastructure on a landscape scale: a 186-metre stone-faced dam, built to create a reservoir and deliberately shaped to become a dramatic waterfall in flood. Its setting in the Elan Valley makes it a strong starting point for exploring the wider water scheme.

Things to do

Verified history
Caban Coch is part of the Elan Valley Water Scheme and was built to create Caban Coch Reservoir. Coflein records construction beginning in 1893, with work on the foundations starting in 1894 and on the dam itself in 1896. The Elan Valley account describes it as the first dam to be worked on. It is 37 metres high and 186 metres long. The same account says stone from a nearby quarry was used inside the dams, while sandstone for the facing was brought from the Vale of Glamorgan. Compensation water is released from the dam into the River Elan under a provision made when Birmingham Corporation bought the Elan Valley estate.
Hidden details
The facing stone came from far away — The Elan Valley account says the dam’s facing sandstone was brought from the Vale of Glamorgan, while stone from a nearby quarry was used inside the dams.
A name meaning “Red Cabin” — The Elan Valley website gives the meaning of Caban Coch as “Red Cabin”.
