Gorham's Cave Complex

Cave in Gibraltar

Inscribed on Unesco's World Heritage list in 2016, these four archaeologically rich cliffside caves on Gibraltar's southeastern coast were inhabited by Neanderthals from around 127,000 to 32,000 years ago, making them a key source for modern-day debates about human evolution. Dolphin Adventure runs boat trips to (but not into) the caves on demand, with historical commentary (£25 per person; minimum six people). You can see finds from the caves at the town-centre Gibraltar Museum.

A new interpretation centre and viewing platform were in the works at the time of writing.
