Cadw's description

In a sheltered location set within the cliffs on the NW side of Porth Dafarch, NW of Trearddur Bay.

Built as customs post in 1819, when a harbour was completed at Porth Dafarch; built to allow mail and passengers to be landed on Holyhead Island when N winds made landing at Holyhead impossible. In 1873 the new harbour at Holyhead was completed, making the one at Porth Dafarch redundant.

Square, single storey structure; built abutting the cliff face which forms one side of the structure, the other 3 sides of local rubble, a flat cement roof. Openings with segmental-arched stone heads; single entrance doorway in seaward facing side and single window in right return. In poor condition, June ' 98.

Contains a barrel vaulted ceiling of red brick.

Listed as an unusual example of a customs post and coastal landmark of local historical interest.
