On a low mound in the NE corner of a field behind the Harp pub 100 yards east of Haverfordwest Road (A40).
OPEN All surface features remain intact but the tops of both ventilation shafts have become detached, one lies in the grass nearby the other is at the bottom of the shaft. The FSM pipe is encased in concrete. There is some erosion around the concrete apron. The hatch is open although the hinge has seized making it is difficult to lift. The only remaining artifacts inside the post are three single beds.
An Orlit B stands alongside in reasonable condition.
Opened in 1960 and closed in 1968.
