The Céide fields in Ballycastle, Co Mayo, date back 5,500 years, making them the world’s oldest field systems, with a complex of walls, houses and tombs, protected beneath a bog and is the largest Stone Age site on the planet. It is the most extensive Neolithic site in Ireland.

Discovered in the 1930s by schoolteacher Patrick Caulfield, his son Seamus having studied archaeology, began to investigate the site further and revealed the complex system hidden for centuries.

The remains tell a story of the everyday lives of a farming people, their organised society, their highly developed spiritual beliefs, and their struggle against a changing environment beyond their control.
