Anglesey (Ynys Môn): island county of northwest Wales

Geography and settlements

Anglesey's landscape ranges from low-lying agricultural plains to cliffs and dunes. The island is linked to the Welsh mainland by major bridges spanning the Menai Strait and by road connections such as the A55 trunk road. Principal settlements include:

• Holyhead — main port and transport hub
• Llangefni — a central market and administrative town
• Amlwch, Beaumaris and elsewhere — smaller towns with historic centres

The island has notable coastal reserves and stacks where seabirds breed, and several sandy beaches popular with visitors.

History and heritage

Anglesey has a long human history with prehistoric monuments, burial mounds and standing stones. In the medieval period the island was important for religious houses and later for fortifications; Beaumaris Castle, in particular, is part of a group of medieval castles recognised for their historical significance. Local folklore also preserves earlier Celtic and Druidic associations.

Economy, transport and tourism

Traditionally an agricultural area, Anglesey's economy also includes tourism, shipping and services. Holyhead provides ferry links across the Irish Sea, while local roads and rail connections tie the island to the rest of Wales. Visitors come for coastal walks, birdwatching reserves and historic towns. Well-known natural attractions include sea cliffs, dune systems and offshore islets that support diverse wildlife.

Culture and notable features

Welsh language and culture remain strong on the island, and many communities use Welsh as a first language. A widely recognised curiosity is the long place name of the village often shortened in speech — Llanfairpwllgwyngyllgogerychwyrndrobwllllantysiliogogogoch — commonly abbreviated to Llanfair PG in everyday use. The island's cultural calendar blends traditional festivals, community events and attractions aimed at visitors.
