The walls are all that survive of this small Roman fort dating to the late 3rd century. The fort stands to the west of Holyhead harbour, and was built around 300 AD as a defence against Irish pirates. Construction of this fort took place at the same time as the Saxon shore forts along the south east coast of England, and was probably part of the same concerted efforts by the Roman elite to retain control of their British possessions.
