Around 4000 years ago, eight or more people were buried in Càrn Ban. One was a woman, laid on one side with her legs curled up to fit into the small stone chamber. White quartz rocks and pottery urns were buried with her, perhaps because they were believed to be important in the afterlife. In 1792, four of these chambers or cists were uncovered by local people as they took the stone away to build dykes, but when they opened them, they were hit with an intolerable stench that gave them violent headaches.
