At the facade of the cave is a relief of various menacing creatures and demons carved right into the rock at the cave entrance. The primary figure was once thought to be an elephant, hence the nickname Elephant Cave. The site is mentioned in the Javanese poem Desawarnana written in 1365. An extensive bathing place on the site was not excavated until the 1950s.These appear to have been built to ward off evil spirits. (Wikipedia)
