Geevor is much more than a mine. Underground was just the beginning. 

There’s just as much to see and learn from the surface buildings at Geevor Tin Mine. About two- thirds of the work force of the tin mine actually worked above ground, in jobs that supported the underground or helped to process the ore into tin concentrate, the mine’s finished product.
