Holyhead Breakwater

Holyhead Breakwater is situated at the north-western end of Holyhead on the island of Anglesey in North Wales. The Victorian structure, which is 1. 7mi long, is the longest breakwater in the United Kingdom. The breakwater, which is accessible in good weather, has a promenade on top which leads out to the Holyhead Breakwater Lighthouse. ConstructionThe purpose of the project was to enclose more than 400acre of deep water to create a sheltered roadstead, in addition to Holyhead's pre-existing 276acre harbour. In 1848 the Chester and Holyhead Railway opened, dramatically increasing the amount of sailings between Ireland and Great Britain. Work began in 1845 under the auspices of superintendent engineer J. M. Rendell. Following his death in 1856, the project was completed by John Hawkshaw. Up to 1, 300 men were employed during the project, of whom more than forty lost their lives. 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. Divers in submarine bells created the level foundations on which the tiers of facing stones were placed. These men worked underwater using picks and hammers, and carried out blasting using gunpowder sealed in watertight tin pipes.
