History

The leat is contemporary with the watermill which is earlier C19; it may be contemporary with the rebuilding of the house. As built it was an estate water mill providing flour etc. but turbines were later installed so that it could provide electric power for the immediate estate.

Glynllifon was the seat of the Wynn family and Sir Thomas John Wynn became the 1st Lord Newborough in 1776. The house was rebuilt after a fire 1836-48 by Edward Haycock, architect of Shrewsbury.

Exterior

Deep stone-walled and cement-rendered leat curves around from the west drive to reach wheel pit powering the overshot waterwheel. On the north-west side is a square reservoir with its own iron sluice gates. Close to the wheel is the surviving paddle for operating the main sluice, part of which remains. Beyond this the leat steps down and runs the remaining distance within a slate-lined trough.

Reasons for Listing

Included for group value with the Watermill as an unusually well-preserved example of a leat serving an estate mill.
