Caves of Caiplie
The Caves of Caiplie, Caplawchy or Caiplie Coves, known locally as The Coves, are a cave system on the Fife Coastal path between Anstruther and Crail in Scotland. The caves were used by farmers to house livestock and as a doocot, around 170 CE. The caves are thought to have been abandoned since 180 CE. In the 9th century they were reputedly the site of early Christian worship.
