The Mining Heritage of Goslar.

I returned to Goslar today to try to do one of the 4 hour underground mine tours but ended up on a much shorter tour of some of the tunnels and workings - unfortunately all in german.

This mining area, just north of Goslar, is also an UNESCO world heritage site.  Here water has been used extensively to develop the mines and crush the ore for the extraction of silver, lead, tin and copper; ever since the middle ages (11th century) until the 1980's. There are huge water wheels, drainage ditches and canals which are quite unique  in the history of mining.
