As the remotest part of the British Isles, the islands of St Kilda, 40 miles west of the Outer Hebrides, form the most important seabird breeding site in northwest Europe. Today, the area is a UNESCO World Heritage Site because of its beauty and wildlife. With cliffs, sea stacks and grassy slopes, the islands are ideally suited to nesting birds like puffin, kittiwake, fulmar, razorbill and guillemot. They also host the largest population of breeding gannets in the world. Now managed by the National Trust for Scotland in partnership with Scottish Natural Heritage and the MoD.
