St Kilda was permanently inhabited for at least two millennia, its population probably never exceeding 180 (and certainly no more than 100 after 1851). The entire population was evacuated from Hirta (the only inhabited island) in 1930. Currently, the only permanent residents are defense personnel although a variety of conservation workers, volunteers and scientists spend time there in the summer months. Occasionally a very lucky tourist may get the chance to visit as part of an organised boat trip or even as part of a North Hebrides cruise.

This was the first film to be shot on St. Kilda, the later film from 1928 ‘St. Kilda - Britain's Loneliest Isle’ is shown below and is concerned more with the population that would later be evacuated from the island. This earlier film was by the pioneering bird cinematographer, Oliver Pike, and focuses on the island's bird population, as well as the St. Kildans' remarkable methods of snaring sea birds for food and gathering eggs from the precarious cliff face. To achieve the spectacular shots of the bird colonies and birds in flight, Pike had to develop his climbing skills, with the aid of the locals, burdened as he was with a heavy film camera. It may take a while to view all of these films, but I think its worth the effort.
