In the Bay of Gibraltar, researchers have made one of the most significant archaeological discoveries in recent years. What initially appeared to be isolated historical traces beneath the seabed has, through extensive investigation, revealed itself to be a vast maritime archive: an underwater landscape filled with shipwrecks, anchorage sites and relics that reflect more than 2,500 years of maritime history.

The discovery is part of the research project “Project Herakles”, led by the University of Cádiz. Over several years, scientists systematically mapped the seabed of the region, with surprising results. In total, 151 archaeological sites were identified, including 124 shipwrecks spanning different historical periods.
A journey through maritime history
The finds paint an exceptionally clear picture of the historical significance of the Strait of Gibraltar. As early as the 5th century BC, ships were already sailing these waters, including a Punic merchant vessel from the time of Carthage. This means that the documented use of the region as a maritime trade route stretches far back into antiquity.
Over the following centuries, Roman merchant ships, medieval vessels from the period of Islamic rule in Al-Andalus, and numerous wrecks from the early modern era all followed. Particularly striking is the high proportion of merchant ships, which researchers estimate account for around 81% of the finds. This highlights the region’s central role as one of the most important maritime trade corridors between the Atlantic and the Mediterranean.
A global crossroads for millennia
The discoveries also show that the Bay of Gibraltar was never only of regional importance. Among the wrecks are ships from Spain and Great Britain, as well as from the Netherlands, Venice and other European trading powers. For centuries, the region served as an international transport hub where trade routes, cultures and political interests intersected.
Finds from the 20th century also demonstrate that maritime activity in the bay continued into modern times. These include, among other things, remains of early aviation and military activity, completing the picture of a historically continuously used area.
Unexpected details from the deep
In addition to the large historical shipwrecks, archaeologists also uncovered surprisingly intimate traces of past crews. Particular attention was drawn to a small 18th-century Spanish warship, where a wooden box was discovered. It was initially assumed to contain important documents or military records, but in fact it held only wooden combs – likely personal belongings of an officer.
Such details provide researchers with a rare insight into everyday life aboard historical ships, making the finds far more than merely of military or economic interest.
A heritage in danger
Despite the significance of the discoveries, the underwater cultural heritage of the region is under serious threat. Scientists warn of several risks: intensive port activity, dredging operations, rising sea levels, and invasive algae species are increasingly damaging the fragile structures. Many of the wrecks are in a delicate condition and could be lost irretrievably without protective measures.
To preserve this unique maritime heritage, researchers are increasingly relying on digital technologies. Using 3D scanning and virtual reconstructions, the sites are documented and converted into digital models. These can then be explored in virtual environments without damaging the original remains.
The aim is to enable both scientific analysis and public access, while also protecting the physical remains on the seabed.
