Dún Briste (Gaelic for Broken Fort) was once joined to the mainland. The sea stack stands 45 metres (150 feet) tall. This structure and the surrounding cliffs were formed around 350 million years ago (during the 'Lower Carboniferous Period'), when sea temperatures were much higher and the coastline at a greater distance away. There are many legends describing how the Sea Stack was formed but it is widely accepted that an arch leading to the rock collapsed during very rough sea conditions in 1393. This is remarkably recent in geological terms.
