What is the significance of St Davids in ancient history?

Ancient Britons dubbed the St Davids area a “thin” place, where the gap between Earth and Heaven was small. Rimmed in a shoreline of bizarre rock formations, deep coves, and dreamy fishing villages, this is still a spiritual spot: full of millennia-old burial mounds and the end point of a major mediaeval pilgrimage route. A feeling of serenity remains, and there is no better way to experience this than camping out on the crag-dotted grasslands around Britain’s westernmost city, St Davids itself.
