Holyhead (/ˌhəʊliˈhɛd, ˌhɒliˈhɛd/;^[3][4] Welsh: Caergybi Welsh pronunciation: [kɑːɨrˈɡəbi] , "Cybi's fort") is a historic port town, and is the largest town and a community in the county of Isle of Anglesey, Wales. Holyhead is on Holy Island, bounded by the Irish Sea to the north, and is separated from Anglesey island by the narrow Cymyran Strait, having originally been connected to Anglesey via the Four Mile Bridge.^[5]

In the mid-19th century, Lord Stanley, a local philanthropist, funded the building of a larger causeway,^[6] known locally as "the Cobb". it now carries the A5 and the railway line. The A55 dual carriageway runs parallel to the Cobb on a modern causeway.^[7]

The town houses the Port of Holyhead, a major Irish Sea port for connections towards Ireland.^[8] The population of the town proper as of the 2021 census was 12,084, an increase on the 2011 census.^[9]

The town's English name, Holyhead, has existed since at least the 14th century. As is the case with many coastal parts of Wales, the name in English is significantly different from its name in Welsh. It refers to the holiness of the locality and has taken the form Haliheved, Holiheved, Le Holyhede and Holy Head in the past. The Welsh name, Caergybi, derives from the fortification around which the town developed. The locality was known by such names as Karkeby ('seat of Cybi'), Castro Kyby ('the fortified military camp of Cybi'), and Kaer Gybi (Cybi's resting place).^[10]

Prior to the influence of the fort on the name, the hamlets which came before it were likely known as Llan y Gwyddel ('church/parish of the Irish') and Eglwys y Beddi ('church of the graves').^[11]

Holyhead Old Town is built around St Cybi's Church, which is built inside one of Europe's few three-walled Roman forts (the fourth boundary being the sea, which used to come up to the fort). The Romans also built a watchtower on the top of Holyhead Mountain inside Mynydd y Twr, a prehistoric hillfort.^[12]

Settlements in the area date from prehistoric times, with circular huts, burial chambers and standing stones featuring in the highest concentration in Britain. The current lighthouse is on South Stack on the other side of Holyhead Mountain.^[13]

Soldiers Point Hotel, located near the breakwater park in Holyhead, was first established in 1848. The residence of an engineer was in charge of the government-sponsored alterations to Holyhead Harbour being carried out. It was badly damaged in a fire in 2011.^[14]

Holyhead has three officially designated Conservation Areas. Holyhead Central Conservation Area covers the historic Old Town core that developed around the Roman Fort. Holyhead Beach Conservation Area in located in the Newry promenade area, and Holyhead Mountain Conservation Area is located north of the village of Llaingoch.^[15]

In the early nineteenth century, it was still undecided which port would be chosen as the primary sea link along the route from London to Dublin: Porthdinllaen, on the Llŷn Peninsula, or Holyhead in Anglesey. In May 1806, a parliamentary bill approved new buildings in Porthdinllaen when it seemed that the town would be chosen. Porthdinllaen was almost as far west as Holyhead, but Holyhead was more accessible because of Thomas Telford's road developments. Porthdinllaen Harbour Company was formed in 1808 in preparation, but the bill before Parliament to constitute Porthdinllaen as a harbour for Irish trade was rejected in 1810.^[16]

Holyhead's maritime importance was at its height in the 19th century with a 1+3⁄4-mile-long (2.8-kilometre) sea breakwater. Holyhead Breakwater, built to create a safe harbour for vessels caught in stormy waters on their way to Liverpool and the industrial ports of Lancashire; it is the longest breakwater in the UK.^[17]

Throughout the later 18th century and the entire 19th century, Holyhead was a crucial transit point for landed gentry and British parliamentarians and military officials who were travelling from Ireland to London. It was also a transit point for British owners of multinational estates visiting their 'other lands' or London houses. The port of Holyhead saw significant development throughout the 19th century to accommodate the growing passenger traffic between Holyhead and Dublin, which reached approximately 14,000 passengers annually by 1814. Key improvements made after the 1800 Act of Union with Ireland included the illumination of the South Stack Lighthouse in 1809, the construction of a built-up harbor in 1810, and the addition of a substantial breakwater between 1848 and 1873. Although mail service through Holyhead was temporarily suspended in 1838 in favour of rail transport through Liverpool, the development of the north Wales coastal railway in 1850 led to its reinstatement.^[18]

The post road built by Thomas Telford from London strengthened Holyhead's position as the port from which the Royal Mail was dispatched to and from Dublin on the Mail coach. The A5 terminates at Admiralty Arch (1822–24), which was designed by Thomas Harrison to commemorate a visit by King George IV in 1821 en route to Ireland and marked the zenith of Irish Mail coach operations. Holy Island and Anglesey are separated by the Cymyran Strait which used to be crossed on the Four Mile Bridge; so called, because the bridge was 4 miles (6 kilometres) from Holyhead on the old turnpike.^[5]

With the opening of the railway from London to Liverpool, Holyhead lost the London-Dublin mail contract in 1839 to the Port of Liverpool. Only after the completion of the Chester & Holyhead Railway in 1850, and the building of Holyhead railway station, did the Irish Mail return to Holyhead, operated from London Euston by the London & North Western Railway.^[19]

The Port of Holyhead is a busy ferry port. Stena Line, Northern Europe's biggest ferry company, operates from the port, as do Irish Ferries. Ferries sail to Dublin.

Holyhead railway station is the terminus of the North Wales Coast Line and is currently served by Avanti West Coast and Transport for Wales services. Avanti West Coast runs direct trains to London Euston via Crewe^[20] and Transport for Wales operate direct trains to Cardiff and Birmingham International, via Wrexham and Shrewsbury; they also operate on the route to Manchester Piccadilly, via Warrington.^[21]

The rail and ferry terminals are connected (for pedestrians and cyclists) to the town centre by The Celtic Gateway bridge.^[22]

The Stanley Embankment, or The Cob, connects Anglesey and Holy Island. It carries the North Wales Coast Line railway and the A5 road. The embankment was designed and built by Thomas Telford. When the A5 was being constructed between London and the Port of Holyhead, a more direct route was needed. Construction started in 1822 and was completed a year later.^[23] It gets its formal name after John Stanley, 1st Baron Stanley of Alderley, a significant local benefactor.^[6]

In 2001, work was completed on the extension of the A55 North Wales Expressway from the Britannia Bridge to Holyhead, giving the town a dual carriageway connection to North Wales and the main British motorway network. The A55 forms part of Euroroute E22. The Anglesey section was financed through a Private Finance Initiative scheme.^[24]

Local bus services are provided primarily by Arriva Buses Wales, who operate services around Anglesey and to Bangor.^[25]

Until September 2009, Holyhead's main industry was the massive aluminium smelter on the outskirts of the town, operated by Anglesey Aluminium, a subsidiary of Rio Tinto. A large jetty in the harbour received ships from Jamaica and Australia, and their cargoes of alumina were transported on a rope-driven conveyor belt running underneath the town to the plant. The jetty is now available to dock visiting cruise ships.^[26]

The plant relied for its electricity supply on Wylfa nuclear power station, near Cemaes Bay. However, Wylfa was reaching the end of its life and had permission to generate only until 2012.^[27] On 18 October 2010, the British government announced that Wylfa was one of the eight sites it considered suitable for future nuclear power stations.^[28]

Holyhead Port is a major employer, most of the jobs linked to ferry services to the Republic of Ireland operated by Stena and Irish Ferries. Other significant industrial/transport sector employers in Holyhead include Holyhead Boatyard, Gwynedd Shipping and Eaton Electrical, with the last of these having seen many job losses in 2009.^[29]

Until the end of 2020 the port, which employs 250 (in 2021), was the second busiest roll-on roll-off port in the UK after Dover with around 450,000 lorries taking ferries to Dublin. Following the Brexit withdrawal agreement, freight traffic from Ireland fell by 50% in January 2021.^[30]

Like the rest of Wales and the British Isles, Holyhead has a maritime climate (Cfb according to the Köppen climate classification) with cool summers and mild winters, and often high winds exacerbated by its location by the Irish Sea. The nearest official weather observation station is at RAF Valley, about five miles (eight kilometres) southeast of the town centre.^[31]

On 23 November 1981, Holyhead was struck by two tornadoes during the record-breaking 1981 United Kingdom tornado outbreak. One of the tornadoes, rated as an F2/T4 tornado, was the strongest recorded out of 104 tornadoes in the entire outbreak, causing damage to around 20 properties in Holyhead and destroying a mobile home.^[32]

There are two tiers of local government covering Holyhead, at community (town) and county level: Holyhead Town Council and Isle of Anglesey County Council. The town council is based at Holyhead Town Hall on Newry Street. It comprises sixteen councillors elected from the seven community electoral wards.^[34]

The ancient parish of Holyhead covered the majority of Holy Island.^[35] In 1832 a parliamentary borough was established covering just the area around the town itself, as a contributory borough to the Beaumaris Boroughs constituency.^[36]

In 1860 a local government district was created covering the same area as the parliamentary borough, governed by an elected local board.^[37] Such local government districts were reconstituted as urban districts under the Local Government Act 1894. As part of the 1894 reforms, parishes were no long allowed to straddle district boundaries, and so the part of Holyhead parish outside the urban district became a separate parish called 'Holyhead Rural'.^[38]

Holyhead Town Hall was completed in 1875 and served as both a public events venue and meeting place for the local board and the urban district council which replaced it.^[39][40] Holyhead Urban District was abolished in 1974, with its area instead becoming a community. District-level functions passed to Ynys Môn-Isle of Anglesey Borough Council, which in 1996 was reconstituted as a county council.^[41][42] The Holyhead Rural parish also became a community in 1974, and was renamed Trearddur in 1984.
