History

The island takes its name from Old Norse, Svíney or Swefney, meaning either "Swine Isle" or "Sweyn’s Isle".

There are prehistoric, pre-Norse and Norse remains on the island. as well as the remains of more recent crofting settlement including a herd of feral cattle. The island was populated from around 500 BC until 1974.

Boats were built on the island for a number of years. The last of these, the Hood can be seen pulled well up the shingle beach by the landing stage. It is no longer seaworthy, having a hole in it caused by the feral cows using it as a rubbing post. The landing stage and boat can be seen briefly in passing through a gap in the rocks near the north end of the island on the east side. The last house to be occupied can also be seen in this area.

The island was the site of many shipwreck

s caused by the strong currents in the Pentland Firth. In 1931, a 6,000 ton Danish freighter called Pennsylvania was wrecked on the island. The Orkney newspaper of the time said that it was one of the most richly-laden ships that was ever wrecked in the area. After some salvaging, the wreck was finally bought by a syndicate of Stroma and Swona men.

The Swona Minor light was built in 1906 on the south west tip of Swona. It was originally a cast iron tower but was replaced by a reinforced concrete square tower sometime in the 1980s. The earlier Stroma Lighthouse was built in 1896 and stands at the northern end of Stroma island.

In summer 1973 Arthur Rosie left the island and died shortly afterwards. James and Violet Rosie (brother and sister) left in March 1974. James had Parkinsons Disease and died c. 1976 of a perforated stomach ulcer. Violet died c. 1984 in South Ronaldsay. They did not return to the island after they left it. Many of the houses, while in a state of dilapidation, are as they were left, with various possessions still to be seen where they were abandoned.

 was still going strong, and is now classified as a new breed. It then consisted of ten bulls, four cows, and two calves. This appears to be around the maximum number that the island can support. Two calves are born each spring, although not all live to maturity. The herd gets no additional feed, although it is checked by a vet each year. The animals are self-selecting for hardiness, easy calving, and low-maintenance, feeding off the grass and seaweed. Having been separated from the mainland for so long, they are completely disease-free, and have reverted to wild behaviour. Because of this, DNA

samples have been taken, from the ears of some of the cattle that died. In the summer the main herd is usually in the centre of the island.
