A major new exhibition, Trysor, opens this Saturday, 28 March, 10am at Oriel Môn, shining a spotlight on the island’s extraordinary archaeological heritage from Neolithic through to the medieval period.

Trysor (the Welsh word for treasure) brings together an exceptional selection of artefacts from Oriel Môn’s collection alongside newly acquired treasure finds. Highlights include the only Iron Age gold coin hoard ever discovered in Wales, as well as newly uncovered objects from Llyn Cerrig Bach one of the most significant archaeological sites in the country.

Many of the objects featured in the exhibition will be on public display for the first time, offering visitors a rare and compelling opportunity to engage with Anglesey’s rich and varied past. From everyday items to remarkable treasures, the exhibition reveals the depth, diversity and importance of the island’s archaeological record.

By presenting these finds together, Trysor invites audiences to explore the stories behind the objects and the people who once lived on Anglesey, highlighting the island’s long-standing cultural and historical significance.

Kelly Parry, Senior Manager, Oriel Môn said: “Through a fascinating variety of objects discovered on Anglesey, Trysor explores the idea of treasure in its broadest sense - from legally defined treasure finds to objects that are rare, beautiful, and meaningful. This exhibition also celebrates the strength and growing significance of Oriel Môn’s archaeology collection, as new discoveries continue to transform our understanding of Anglesey’s rich history.”

The exhibition opens to the public on Saturday, 28 March at Oriel Môn and will come to an end 4 April 2027.

Oriel Môn is open Tuesday to Sunday, 10am to 5pm, and on bank holiday Mondays, admission is free.
