About Oriel Ynys Môn
Oriel Ynys Môn — the Gallery of Anglesey — is the island's principal museum and art gallery, purpose-built in 1991 in Llangefni beside the River Cefni. Free to enter, it brings together three distinct collections: an art gallery with an outstanding holding of work by Charles Tunnicliffe; natural history galleries covering the geology, habitats, and wildlife of Anglesey; and archaeological displays from sites across the island, from the Neolithic to the early medieval period.
Charles Tunnicliffe (1901–1979) is the collection's centrepiece. One of the most precise and celebrated British wildlife artists of the 20th century, Tunnicliffe moved to Anglesey in 1947 and spent the rest of his life at Malltraeth on the island's south coast, sustained by its exceptional birdlife. The museum holds hundreds of his works — including the famous measured drawings, painted to exact scale as both art and scientific record. For birdwatchers and natural history enthusiasts, the collection is exceptional.
The natural history galleries interpret Anglesey's remarkable ecological range — a 125-mile coastline encompassing sea cliffs, tidal flats, machair grassland, and raised peat bogs, supporting bird populations of national importance. The archaeology collection draws on finds from Bryn Celli Ddu, Din Lligwy, and other key sites, reflecting Anglesey's Iron Age significance as a druidic stronghold and its subsequent Roman conquest in AD 60–61.
