St Kilda, United Kingdom (2005)

The archipelago of St Kilda in the Outer Hebrides of Scotland was originally inscribed as a natural heritage site in 1986 following recommendation by IUCN, due to its superlative natural features and habitats for rare and endangered species of birds. ICOMOS also recommended in 1986 that the property should be listed for a cultural criterion (relating to traditional human settlement), stating that “the St. Kilda archipelago corresponds perfectly to the definition of a cultural and natural property whose value should be taken into consideration in an evaluation complementary to that of IUCN”, however this was not executed by UNESCO.
