Sumburgh Head Lighthouse
The lighthouse was built by Robert Stevenson in 1821 and is the oldest lighthouse on Shetland. From 1906 until 1987 there was also a foghorn, which is traversable in azimuth. This replaced a fog bell which had been presented after the loss of the "" in 1864. The bell now hangs in the parish church at Dunrossness. The light was automated in 1991 and the keepers' houses were converted into holiday accommodation. The lighthouse complex also has offices for the RSPB who look after the bird reserve which surrounds the lighthouse.
