There is a small lagoon in the interior of the island to the northeast.
In 1941, during World War II, gun emplacements were installed on the southern point of the island and manned by Ceylonese troops.
[3] This island is named after James Horsburgh, hydrographer to the East India Company and author of the long-titled "Directions for Sailing to and from the East Indies, China, New Holland, Cape of Good Hope, and the interjacent Ports, compiled chiefly from original Journals and Observations made during 21 years' experience in navigating those Seas".
Horsburgh's Directory was the standard work for oriental navigation in the first half of the 19th century, until Robert Moresby's survey of the Archipelagoes of the Central Indian Ocean when for the first time in history accurate maps of atolls like Keeling or Cocos were published.
