Excelsior Tunnel, Kit Hill

Excelsior Tunnel, Kit Hill
In an attempt to explore the ground beneath Kit Hill, in the Tamar Valley mining region, two long tunnels were constructed. Neither reached significant and important mineral deposits.This one, the Excelsior, was begun in 1881 and continued at intervals until 1938. It was last used for underground atomic explosion tests. The other tunnel, on the opposite side of the hill was driven for half a mile towards the Princess of Wales mine and was intended to link to this, but this never happened.
