About

About Spartel Island (Bank) – Atlantis Hypothesis Locus

Submerged seamount paleo-island 15 km NW of Cape Spartel (Tangier) at –56 m (Majuan/Spartel Bank), identified 2001 by French geologist Jacques Collina-Girard as Plato's Atlantis on bathymetric reconstructions: at –135 m LGM it was 10–12 km archipelago westernmost before Pillars of Heracles. Drowned by Meltwater acceleration ~11,600 BP (end Younger Dryas), alleged correlate to Plato's 9,000 years before Solon. Antiquity (2004) critical commentary (Rainer Kühne response) questioned identification; Marseilles expedition planned never confirmed megacity. Mainstream: natural shoal, no artefacts. Remains popular 'most credible geology Atlantis' claim.

Why it mattersTextbook case of bathymetric paleogeographic reconstruction illuminating strait palaeo-archipelagoes; often taught as cautionary hypothesis-vs-evidence study.
