Long Hole, also spelled Longhole, is a limestone cave on the south coast of the Gower Peninsula between Paviland and Port Eynon. It is relatively small, measuring about deep after several excavations. It was first excavated in 1861 by Colonel E. R. Wood. Wood found evidence of a lithic assemblage and faunal remains. The faunal remains included cave hyena, reindeer, Woolly rhinoceros, mammoth, straight-tusked elephant and wild horse. Read more on Wikipedia
