Admiralty Arch, in Holyhead, Anglesey, was built in 1824 to mark the end of Thomas Telford's Holyhead road. The arch was designed by Thomas Harrison and its main purpose was to commemorate the visit of King George IV of the United Kingdom in August 1821. The King arrived in Holyhead on the royal yacht Royal George on the 7 August, continuing to Plas Newydd where he stopped overnight. He returned the next day to his yacht, but due to poor weather his departure was delayed and the decision was made to transfer to the steam packet Lightning which conveyed him on the 12 August to Howth, near Dublin for his state visit to Ireland. The change to the packet boat was met with widespread approval.Funded through public subscription the structure took two years to complete and was made of stone quarried at Red Wharf Bay on the eastern side of Anglesey. Due to its history it is known alternatively as the George IV Arch by the Royal Commission on the Ancient and Historical Monuments of Wales or the Triumphal Arch. The Grade II* listed arch is situated within the Port of Holyhead on Ynys Halen and cannot be accessed by the public due to safety reasons. In 2017, plans to move it to a more open location were mooted. At present the best place from which to view it is from St Cybi's Churchyard.At the seaward end of the Admiralty Pier, beyond the arch, is the Grade II listed Holyhead Mail Pier Lighthouse, completed in 1821 it was designed by John Rennie as part of extensive improvements to Holyhead Harbour.

The Celtic Gateway (Welsh: Porth Celtaidd) is a stainless steel pedestrian and cycle bridge located in Anglesey, Wales. Opened on 19 October 2006 by Andrew Davies AM to better connect Holyhead's railway station and ferry terminal with the town centre for pedestrians and cyclists. The distance between the two was originally 830 metres, including two steep inclines and the crossing of a busy road. A 1991 bridge reduced the distance to 585 metres with one steep incline but with the road crossing still needed. The current bridge has one shallow incline and cuts the distance to 280 metres with no roads to cross. Crossing the Old Holyhead Harbour, the North Wales coastal railway line and the A5154 (formerly the end of the A5), this 160-metre-long (520 ft), 7-metre-wide (23 ft) structure was built in the futuristic architectural style by the Italian company Cimolai. The whole length of the bridge is wheelchair and pram accessible. The Gateway is further enhanced by a number of artworks. These include: "Sun boats", a series of bronze plaques which have been built into the bridge paving. The sun boat image is derived from the sun-worshipping Celts who believed it travelled across the night sky in a boat; 'Porth Celtaidd - Celtic Gateway' a series of Venetian Glass mosaic by artist Gary Drostle.

Eglwys y Bedd ("Church of the grave") (sometimes referred to as Llan y Gwyddel, or "Church of the Irishman") is all that remains of a 14th-century church in Anglesey, north Wales. It is set within the churchyard of St Cybi's, Holyhead, and may have been built on the site where Cybi (a 6th-century Celtic saint who settled in Holyhead) lived and ministered. It is reputed to house the grave of Seregri, an Irish warrior who lived in the area in the 5th century. It is a Grade II listed building, a national designation given to "buildings of special interest, which warrant every effort being made to preserve them". It housed the first school in Holyhead in the 18th century and is now used by St Cybi's church.

Caer Gybi was a small fortlet in Roman Wales in the Roman province of Britannia Superior. Its name in Latin is unknown. Today it stands at the centre of Holyhead in the Welsh county of Anglesey. Holyhead is named Caergybi in Welsh, after the fort. The fort is one of Europe's only three-walled Roman forts. The fourth side fronted the sea and was probably the site of a quay. Its date is unknown, but it is generally thought to be part of a late-4th-century scheme, associated with Segontium, which was used to defend the west coast against Irish sea-raiders. The Romans also built a watch tower, within Mynydd y Twr on the top of Holyhead Mountain, which was almost certainly used as the fort's look-out point. Both were possibly abandoned around 393, when the troops were sent to respond to the revolt of Eugenius of Gaul. In the 6th century, the old fort was given to Saint Cybi, who founded a monastery there. The Church of St Cybi still stands on the site today, with a small detached chapel (Eglwys y Bedd) that reputedly stands over Cybi's grave.
