History

The Shag Rocks were discovered by Jose de la Llana in 1762 with the Spanish ship Aurora, and originally named the Aurora Islands, after his ship. They were visited by the Spanish ship San Miguel in 1769, again by the Aurora in 1774, and in 1779 by the Spanish ships Princesa and Dolores. In 1794 the Auroras were finally mapped by the Spanish corvette Atrevida. However, the Aurora Islands are considered by many to have been a mistaken sighting that was coincidentally near the Shag Rocks, which were known to sealers prior to 1823. They were later rediscovered by James P. Sheffield and given their current name, probably because shags and other seabirds frequent them. They were charted by Discovery Investigations personnel on the William Scoresby in 1927. The first known landing was made in 1956 when Argentine geologist Mario Giovinetto was lowered from a helicopter to collect rock samples.

Government

The Shag Rocks form part of the British overseas territory of South Georgia and the South Sandwich Islands. Before 1985 they came within the Falkland Islands Dependencies.

Argentina lays claim to the Shag Rocks and Black Rock. Black Rock and Shag Rocks are on the route from the Islas Malvinas to South Georgia, on a seamount of Scotia Ridge.

Britain, in 1985, formed its overseas territory of South Georgia and the South Sandwich Islands, which includes Black Rock and Shag Rocks. It now assumes responsibility for preservation and defence of the area.
