The archipelago of St Kilda lies 41 miles west of Benbecula in Scotland's Outer Hebrides.
For more than 4000 years, a community lived in this harsh environment. The people caught seabirds for food, for their feathers and for oil; and they farmed the land for crops.
Contact with the outside world increased in the mid-19th century. And so too did the islanders' dissatisfaction with the realities of life on St Kilda.
They began to rely more on imports of food, fuel and building materials, and on revenue from tourists.
On 29 August 1930, the remaining 36 islanders gave up the struggle against a hostile environment and were evacuated to the mainland.
