Unlikely position on valley floor. On a low mound on the East side of a field boundary, 75 yards North of Abergwesyn Village Hall which is on the opposite side of an un-named minor road.
OPEN All surface features remain intact. There is a metal pipe at the edge of the mound, probably a telephone feed. The hatch is open although the counter balance is detached and lies on the floor below. Internally the post is clean and well preserved with the following artifacts remaining: table, shelf, cupboard, twin bunks, single bed, siren box, BPI mount (detached), GPO connection boxes and wiring and some cardboard boxes that had contained protective clothes. There is a little water on the floor.
An Orlit B stands alongside on the field boundary. Its wooden instrument table is still in place but broken. There are some GPO connection boxes and wiring on the wall.
Opened in 1961 and closed in 1968.
