Project Herakles (University of Cádiz) documented 134 shipwrecks across 151 archaeological sites in the Bay of Algeciras, spanning the 5th century BC through WWII.
Key Takeaways
Three-year survey identified 23 Roman ships, 4 medieval vessels, 24 early modern ships, and a rare 5th-century BC Punic wreck – one of the oldest documented in the region.
The bay’s position at the Strait of Gibraltar made it a mandatory choke point for Phoenician, Roman, Venetian, Dutch, Spanish, and British maritime traffic across millennia.
A late 18th-century Spanish gunboat (Puente Mayorga IV) was recovered – a vessel type frequently mentioned in period reports but almost never studied archaeologically; it disguised as a fishing boat to attack British ships.
Three medieval Islamic-era wrecks could fill a significant gap in Andalucian seafaring records from the late period of Moorish Spain.
Climate change and port development (dredging, dock construction) are active threats; the team is using VR/360 video to build public pressure for legal protection.
Hacker News Comment Review
The dominant thread questions why systematic search took this long given the area’s well-known history as a maritime bottleneck – commenters suspect a combination of funding, permitting, and climate-driven urgency rather than any new methodology.
A commenter adds historical context: Gibraltar’s name derives from Tariq ibn Ziyad, the Umayyad commander whose 8th-century conquest initiated roughly 800 years of Islamic presence in Iberia – directly relevant to the medieval wrecks the team is most excited about.
Notable Comments
@somebehemoth: asks why known high-traffic straits weren’t systematically searched earlier, and whether climate urgency is what finally triggered the project.
