St Kilda is a small archipelago in the North Atlantic, 100 miles west of mainland Scotland.
It was home to a unique community until 1930 and is an important seabird colony. The islands were first inscribed as a natural World Heritage Site in 1986. In July 2004 this was extended to include the surrounding marine environment.
In July 2005 St Kilda became one of the few World Heritage Sites to hold dual status for both its natural and cultural qualities.
