Martin's Cave, Limestone cave on the eastern cliffs of the Rock of Gibraltar
Martin's Cave is a limestone cave on the eastern cliffs of the Rock of Gibraltar, roughly 700 feet above the shoreline. It opens directly toward the Mediterranean Sea and contains natural rock formations along with archaeological deposits.
A British soldier named Martin discovered the cave in 1821 when he fell onto a narrow ledge at its entrance. Excavations in the 1800s uncovered medieval swords, pottery, and tools that document occupation across different time periods.
The cave shows traces of different periods of use that remain visible when you enter the space. These layers tell of people who lived or stayed here over a long stretch of time.
The route to the cave follows the Mediterranean Steps trail and the entrance is secured with a padlock. Visitors should wear sturdy shoes and prepare for exposed conditions, as the path can be windy and has steep sections.
During World War II, electric generators installed in the cave provided power for military operations. Original wiring and drill holes in the ceiling still show evidence of this wartime use today.
