Tomnadashan was a hamlet southwest of Ardtalnaig in Scotland. John Campbell, 2nd Marquess of Breadalbane tried to mine copper, gold, and sulphur there in the 19th century but was unsuccessful.[1][2] The copper mine is best known as the filming location for the Cave of Caerbannog scene in Monty Python and the Holy Grail.[citation needed]
