History

~1744	tunnel created.
1829	tunnel closed and forgotten.
1911	rediscovered by two citizens of Erzenhausener.

Geology

The dripstones in the mine were about 20 cm long and have diameters between 1 cm and 2 cm. They have therefore grown 20 cm in 200 years, which is at least ten times faster than natural stalactites. The speed is because it is not limestone precipitation, presumably the consist of diadochite.

Description

The abandoned mine near Erzenhausen was dug almost 300 years ago in the search for valuable ores. But there was never a valuable ore found and mined. After the closure of the mine it was soon forgotten. It was rediscovered in 1911 by two residents of Erzenhausen, who tried to frame a spring. They discovered that the water came out of the entrance of a walled tunnel.

During the time the tunnel had been left alone huge speleothems formed, and so they called it dripstone cave, although it was not a natural cave. The tunnel was developed and opened to the public, and soon it became a popular tourist destination. Unfortunately all the dripstones have been destroyed during the years, only small remains are left. But at the rear end there are some remains, which continue to grow and may reach the old length in another 100 years.

The mine tunnel is open during summer and closed by a gate during autumn and winter to protect the bats hibernating there. The floor is muddy and maybe flooded a few centimeters, so rubber boots are a good idea. The tunnel is also narrow and low, so we recommend a helmet. There is electric light installed, but it is powered only on special events, so bring a lamp.
