Kents Cavern is the name for a series of caves which stretch underneath the Hopes Nose headland. The limestone caves are notable for their archaeological and geological features and is where a human upper jawbone was found in 1927. The bone has been dated to be approx. 44,000 years old and is the earliest anatomically modern human fossil yet discovered in North-West Europe. The caves are a geological Site of Special Scientific Interest (since 1952) and a Scheduled Ancient Monument (since 1957).
What surface manifestations are there of 'Kent's Cavern'? It sounds a great attraction but has yet to feature on GEOGRAPH. See http://en.wikipedia.org/wiki/Kents_Cavern
