History

The origins of the weir may date back to the medieval period; the Clywedog had long been exploited as a power source prior to the establishment of an ironworks at Bersham at the end of the C17. The weir almost certainly formed part of the water power system for the ironworks during the C18, and then for Bersham Corn Mill from 1828. Its stepped profile was created some time between 1900 and 1911, perhaps to enhance its appearance as a feature within the park at Plas Power.

Exterior

Stepped stonework, slightly curved in plan, with abutment walls of coursed and squared stone to either side, and a blue brick retaining wall linking the weir with Caeau Bridge to the S. A sluice gate at the top of the weir fed a leat which served the ironworks and later cornmill.

Reasons for Listing

Forms a group with Caeau Bridge.

An important element in the early water-power system developed to serve the ironworks (though probably with earlier origins) and subsequently the corn mill at Bersham. The weir also forms a striking feature within Plas Power Park.
