Wookey Hole Caves to 1874 by William Boyd Dawkins, who moved to Somerset to study classics with the vicar of Wookey. On hearing of the discovery of bones by local workmen he led excavations in the area of the hyena den. His work led to the discovery of the first evidence for the use by Palaeolithic man in the Caves of the Mendip Hills. Middle Paleolithic tools have been found in association with butchered bones with a radiocarbon age of around 41,000 years. Herbert E. Balch continued the work from 1904 to 1914, when he led excavations of the entrance passage (1904–1915), Witch's
Wookey Hole Caves gate servicing the paper mill was built about 1852. The tunnel excavated from the third chamber to the ninth chamber and then out to daylight was dug in 1974–1975 by ex-coal miners from the Radstock area. The show cave was further extended in 2015 by excavating a tunnel from the ninth chamber to the 20th chamber. The constant temperature of in the caves is used by Ford Farm of Dorset to mature Cheddar cheese in the 'Cheese Tunnel' – an excavated side tunnel between the ninth chamber and the exit to the show cave. Archaeological investigations were undertaken from 1859
