History

Constructed 1850s and part of a system that pumped water from the River Severn to pools on Moel-y-Mab. The building houses valve rods whereby water pumped from the river at Cilcewydd Mill could be controlled.

The Valve House was part of the Leighton Estate, acquired by the Liverpool banker John Naylor in 1846-47. Here he embarked on an ambitious programme of building, principally Leighton Hall, church and Farm, which was largely completed by the mid 1850s. Naylor introduced new rational farming methods at Leighton, notably pioneering the recycling of manure as fertiliser for which he had to add hydraulic engineering systems on a large scale. Naylor continued to extend and improve the Estate until his death in 1889. His grandson, Captain J.M. Naylor, sold the Estate in 1931.

Reasons for Listing

The Leighton Estate is an exceptional example of high-Victorian estate development. It is remarkable for the scale and ambition of its conception and planning, the consistency of its design, the extent of its survival, and is the most complete example of its type in Wales. The Valve House is an important element of this whole ensemble at Leighton. It is a highly specialised building type which represented a bold attempt to revolutionise agricultural techniques utilising new technology, in the context of a model farm of national significance.
