St Kilda is the UK’s only World Heritage Site listed for both its unique cultural and natural heritage.

With only 24 sites in the world holding dual status, St Kilda shares this designation with Machu Picchu in Peru and Mount Athos in Greece.

The archipelago of St Kilda is located 41 miles west of North Uist in the Outer Hebrides. Formed from the rim of an ancient volcano, it is the remotest part of the British Isles.

New challenges are on the horizon

As Scotland’s largest conservation charity we’ve acted as guardians of this magical place for 60 years. Now, 86 years after the last native St Kildans left, new threats are on the horizon. It’s our mission to make sure the cultural heritage they left behind, and the outstanding natural heritage, isn’t lost too.

Seabirds and habitats are under threat

Climate change and rising ocean temperatures are challenging the precious marine environment and the millions of nesting seabirds it sustains. Damaging storms are crashing into St Kilda’s stacs and cliffs, eroding archaeological treasures that are millennia old.
