Information from Pastscape:
A cave near Burrington Combe, discovered by RF Read in 1919 and excavated by Professors Tratman and Palmer for the University of Bristol Speleological Society from 1919 to 1925 and again in 1929. The bulk of the material discovered relates to use of the cave in the Iron Age, with finds including pottery, antler cheek-pieces, bronze fittings for chariot wheels, part of a bronze bracelet, stone spindle whorls and some iron shackles. Some human remains and a quantity of animal bones were also discovered. The sole find of definite Roman date, a coin of Magnentius, is regarded by Branigan and Dearne as “an accidental contamination of the site”.
It was originally called Keltic Cavern.
