Despite the fact that a Scottish island group and a suburb of Melbourne, Australia, is named after her or him, there never was a St Kilda.
There are numerous theories about how the island got its name, including the suggestion that it is from an old Icelandic word, skildar, meaning shields, referring to the shape of the island. This name may have been mistranscribed by a 16th century cartographer as St Kilda, which was then taken to refer to the fictional St Kilda.
St Kilda is 42 miles from its nearest island neighbour and 112 miles off the coast of Scotland. Its last 36 permanent residents left in 1930 and it has been owned by the National Trust for Scotland since 1957. In 2010, the NTS announced plans to build to islands' first public lavatory to accommodate the needs of the growing number of visitors on cruise ships. .
In 2010, plans were also announced to recruit a mouse catcher for St Kilda in order to assist an Edinburgh University study into the St Kilda Field Mouse, which is unique to the islands and nearly twice the weight of its relatives on the mainland.
