Fodor's Expert Review St. Michael's Cave

This is the largest of Gibraltar's 150 caves; a visit here is part of the tour of the Upper Rock Nature Preserve. This series of underground chambers full of stalactites and stalagmites is sometimes used for very atmospheric (albeit damp) concerts and other events. The skull of a Neanderthal woman (now in the British Museum) was found at the nearby Forbes Quarry eight years before the world-famous discovery in Germany's Neander Valley in 1856; nobody paid much attention to it at the time, which is why the prehistoric species is called Neanderthal rather than Homo calpensis (literally, "Gibraltar Man," after the Romans' name for the Rock, Calpe).
