Tigh nam Bodach means the ‘House of the Old Man’. The bell-shaped waterstones are believed to represent a family – the Old Man or Bodach, the Old Woman or Cailleach and their daughter, Nighean. Local legend suggests that over time the family gets bigger, with new stones reportedly appearing over the years.
Each spring, a local person opens the stone house and places the family of stones outside. Then at the autumn festival of Samhain, the stones are carefully wrapped up in a bed of marsh grass and put back inside.
It is recognised to be the oldest, uninterrupted pagan ritual in Britain, some say in all of Europe.
