The first lighthouse on Flatholm was built in 1738. Converted to oil and partially rebuilt 1820, and a new lantern added in 1866. While the boundary walls may mark an alignment set out in the early period, they may have been rebuilt in the 1860's. The oil store almost certainly dates from this period.


Rough rubble walls c1.5m high enclose an area around the lighthouse, and a trapezoidal area to its NW, the former garden plot. The oil store is built alongside the wall to the NNW, a standard Trinity House design - white-washed render, single storeyed with coped gables and moulded eaves cornice. Camber headed doorway in lower gable end, and a small window (blocked) above it. Similar window in apex of upper gable.

Reasons for Listing

The oil store and enclosure walls form a significant element in the lighthouse site.
