Historical map of the island
Alejandro Selkirk Island

The not permanently inhabited island is 10.4 kilometers long, seven kilometers wide and with an area of ​​about 49.5 km², slightly larger than the second main island of the archipelago, Isla Robinson Crusoe .

The island is named after the Scottish sailor Alexander Selkirk , who was released in 1704 on the neighboring island , which is now called Robinson Crusoe , about 160 kilometers to the east . His fate served the writer Daniel Defoe as a template for his world-famous novel " Robinson Crusoe ".

On the east coast of Alejandro Selkirk Island there are still around 20 buildings from a former convict colony that was in operation from 1909 to 1930. 190 convicts were initially housed there. From 1927 to 1930 there were 160 political prisoners on the island. Today Alejandro Selkirk is only inhabited by about 50 fishermen who are only on the island during the fishing season.

The entire archipelago shows very little erosion, the youngest rocks are one to two million years old. The oval island is formed by rock ridges that break off towards the sea in a cliff. The coastal cliffs are up to 1000 meters high. Deep, cleft-like rock incisions are characteristic of the island's relief. The highest point on the island is the Cerro de Los Inocentes at 1650 meters .

The island is home to the endemic island spiny-tailed hatchet ( Aphrastura masafuerae ), an extremely endangered species of pottery bird . The bird of prey Buteo polyosoma exsul , a subspecies of the red-backed buzzard , only breeds on this island.
