Overview

History & significance

Tai Mawr Leat is a post-medieval industrial watercourse constructed to serve Cyfarthfa Iron Works in Merthyr Tydfil, Wales. The leat was engineered to convey water from the Taff River to power the machinery and furnaces essential to iron production at what became one of the most significant ironworks in Wales during the late eighteenth and nineteenth centuries. This infrastructure represents the substantial hydraulic engineering required to support large-scale industrial operations in the early industrial period. The leat remains a physical testament to the integration of water management systems with the landscape of industrial South Wales.
