The monument structures found at the ruins of Les Fouaillages in Guernsey date back to around 4500 BCE, making it one of the oldest stone monuments in Europe. There is archaeological evidence (flint tools) that suggests that the site was first used around 6000 BCE by ancient hunters. Eventually, the forest was cleared out and a burial ground was built.
The ruins have been well-preserved and were not discovered until 1976 when the nearby area caught on fire. The fire revealed granite slabs arranged in a particular pattern protruding from a mound. Since the site was first excavated, over 60,000 finds have been uncovered and some of them are displayed at the Guernsey museum
