Illa Grossa, the largest of the Columbretes archipelago, was so thick with reptiles that ancient Greek and Roman sailors had named the place for them, calling it Ophiusa and Columbraria. To make it fit for a lighthouse and its keepers, crews set the island alight and let the fire do its work on a population of snakes found nowhere else. It was an act of casual extermination that reads uneasily today, and it says everything about how remote and forbidding this speck of volcanic rock once seemed.

Its shape gives away its origin: a half-ellipse about a kilometre across, curved like the rim of something enormous, because that is exactly what it is....

In 1859 a lighthouse was raised sixty-seven metres above the waves at the archipelago's highest point, and keepers came to live on a rock that offered them almost nothing. In 1895 the Austrian archduke and traveller Ludwig von Salvator published Columbretes, the first full accoun...

The island's strangest chapter came in the late 1970s, when the Spanish and American navies used the Columbretes as targets, bombarding this fragment of unique habitat during military exercises. The shelling continued until 1982, when student protests pressed the provincial autho...

The Columbretes were declared a natural park in 1988, ringed by a marine reserve of more than four thousand hectares in 1990, and reclassified as a natural reserve in 1994. Today no one lives here but the guards posted by the Valencian govern...

Illa Grossa: A Haven in Open Water

The flooded crater at the island's heart forms a near-enclosed cove, one of the only sheltered anchorages across a wide stretch of open sea, and that shelter long made the Columbretes a waypoint for anyone crossing this part of the Mediterran...
