The remote archipelago of St Kilda, off the west coast of the Scottish mainland, is truly an isolated place. It is the most remote part of the British Isles. The wind is so strong here that trees refuse to grow.
In this hostile climate, a small community had clung to their most basic existence, surviving largely by eating sea birds and their eggs. This extraordinary group of men, women and children lived in a hunter-gatherer lifestyle. After thousands of years of isolation, the entire population of the island evacuated to the mainland to escape the failing harvests, the lack of communication and the lack of medical care.
