Mid to late C19 barn, shown on 1st edition Ordnance Survey map surveyed in 1887.

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.


Tall open-sided 6-bay estate hay barn built of honey-coloured stone with red brick dressings under a half-hipped slate roof. Tall opening on gable end facing mill with slate lintel and patterned ventilation holes above. The openings to the right hand (north-west) side have been partly filled in but the original effect is retained to left hand side where they remain open, full-height. Here there is an added corrugated lean-to. The tall opening at the south-west end has also been partly filled in but retains diamond patterned ventilators above. King-post trusses with two tiers of purlins.
