Rammelsberg

The Rammelsberg is a mountain, 635 m high, on the northern edge of the Harz, south of the town of Goslar in the north German state of Lower Saxony. The mountain is the location of an important mine, the only mine which had been working continuously for over 1,000 years when it finally closed in 1988. Since 1992, the visitors' mine of Rammelsberg has become a UNESCO World heritage site.^[1]
