Miners wait in the elevator to be taken up to ground level at a mercury mine that is closing after 500 years. The city of Idrija was a center but now after the price went down on mercury and there is little need for the metal. In the '70s, 1000 men were employed in the mine. Now they are down to a just a few to close it down by filling in tunnels. The run off is loaded with heavy metals and the mine is required to be closed in a non-polluting way. Mercury was first discovered there in 1419.
