Prized for both its natural and cultural heritage, the islands of St Kilda in Scotland's Outer Hebrides are the UK's only mixed UNESCO World Heritage Site. The uninhabited archipelago, known as the islands at the end of the world, provides a habitat for almost a million seabirds, which include the UK's largest Atlantic puffin colony.

A small community occupied St Kilda for thousands of years, though life on the remote outpost was hard. In 1930, the remaining 36 islanders voted to evacuate and relocate to the mainland in search of more favourable living conditions. Now all that remains are the abandoned structures they left behind.
