"Erected about 1879 for Gertrude, wife of Sir Charles T.D. Acland (12th Baronet). Extensive repairs were carried out in 1954. This shelter is open to all for rest and shelter during daylight hours. Please leave it as you would wish to find it and take your litter home."
Apparently Lady Acland's servants used to bring up supplies and she would walk or ride up here and enjoy picnics.
The hut doesn't seem to be a listed building and isn't named on Ordnance Survey maps. There are some benches and a fireplace inside and I have enjoyed several tea breaks there when I have passed it on walks in the area. The hut is located at grid reference SS 922 473, which is just off a bridleway, which runs from the road half a mile east of Selworthy Beacon down to the village of Selworthy. It is about equidistant from the road at the top and the village.
