Wheel o Drams Sculpture

Highlight • Monument

The Wheel o Drams is a sculpture constructed of connected coal mining drams, designed to represent the industrial history of the region. Known locally as ‘the Stargate', it serves as the entry point to Hengoed Viaduct and is an interesting sight along the Taff Vale (Celtic Trail) cycling route. Extra hint: if you’re so inclined, you can climb up inside it and use it as an interesting spot to enjoy a picnic.

Hengoed Viaduct is an old railway viaduct that’s now a walkway and extension of NCN Route 47. It offers a nice view over the valley.

Hengoed Viaduct

Highlight • Monument

The coal mining industry transformed the landscape of South Wales and one of the ways it did that was bringing about the construction of railways and, to span valleys, their accompanying viaducts. Hengoed's viaduct is vast and incredibly impressive. Thankfully, after 35 years of being completely closed, it's now a foot and cycle path, and part of the National Cycle Route 47.
