In the age of sail, northerly winds in the Irish Sea could often prevent ships from Ireland entering the old harbour at Holyhead. When adverse weather conditions halted sailings from Holyhead, passengers and cargo had to be moved to Porth Dafarch on the southerly side of Holy Island.

Construction
In January 1848 work began under the auspices of superintendent engineer J.M.Rendel.[1][4] Following his death in 1856, the project was completed by John Hawkshaw.[4] Shaped 10-tonne blocks of limestone were used to create an outer facing wall, thereby encasing a rubble mound raised from the sea both by dumping from ships and tipping from the shore.[5] Divers in submarine bells created the level foundations on which the tiers of facing stones were placed.[6] These men worked underwater using picks and hammers, and carried out blasting using gunpowder sealed in watertight tin pipes.[6] Up to 1,300 men were employed during the work; 40 died during construction.[7]
