A major archaeological discovery has been made in the Bay of Algeciras, where researchers have identified 151 underwater sites, including 124 shipwrecks highlighting the region’s long-standing maritime significance.
Located near the Strait of Gibraltar, this narrow waterway between Europe and Africa has historically served as a critical global shipping route much like the Strait of Hormuz today.
The survey, conducted between 2020 and 2023 by a team from the University of Cádiz, revealed shipwrecks spanning multiple eras, including the ancient Punic civilization, Roman Empire, medieval times and modern history.
Among the most notable findings is a vessel dating back to the 5th century BC, believed to have transported fish sauce from the southern Spanish city of Cádiz. Researchers also uncovered wrecks linked to the Napoleonic Wars and even remnants from World War II including parts of an Italian naval submarine device.
Lead researcher Felipe Cerezo Andreo noted that many of these wrecks had never been documented before underscoring how little is known about the submerged history of the area. Prior to this study, only four underwater archaeological sites were recorded in the bay.
Experts believe climate change has played an unexpected role in revealing these hidden remains. Shifting ocean currents and sediment movement have gradually exposed wrecks that had been buried for centuries.
Using advanced technologies such as multibeam echosounders and magnetometers, the team mapped the seabed and created digital models of the discoveries. So far, only about a quarter of the identified sites have been thoroughly studied, with many more expected to lie deeper beneath the surface.
Researchers emphasize the urgent need to document and protect these sites, as they provide valuable insights into ancient trade, naval warfare and maritime life across centuries.
