About

Tref Cybi ward encompasses Holyhead town and its immediate surrounding areas on Holy Island, part of Anglesey. The ward includes the busy port area, which handles ferry traffic to Ireland, and the town centre with its mix of retail and residential streets. The landscape transitions from the urban harbour to more open coastal stretches on its edges, providing views across the water.

A dominant feature is the medieval St. Cybi's Church, built within the walls of a Roman fort overlooking the harbour. The ward contains the historic Market Hall and the modern breakwater protecting the port. Life here is closely connected to maritime activities and the daily rhythm of ferry arrivals and departures, underpinning the local economy.
