Holyhead (i/ˈhɒlɪhɛd/ HOL-i-hed; Welsh: Caergybi, "the town of Cybi") is the largest town in the county of Anglesey in North Wales. It is also a major port adjacent to the Irish Sea serving Ireland.
Despite being the largest town in the county, with a population of 11,237 (2001 census), it is neither the county town nor actually on the island of Anglesey. With other Holy Island settlements and nearby Valley, Anglesey, the population of the Holyhead area is 16,000. Holyhead is located on Holy Island. It was originally connected to Anglesey via Four Mile Bridge, so called because it was four miles (6 km) from Holyhead on the old turnpike Road to London. In the mid 19th century, Lord Stanley, a local philanthropist, funded the building of a larger causeway, known locally as "The Cob", it now carries the A5 and the railway line. The A55 dual carriageway runs parallel to the Cob on a modern causeway.
