After a week fighting with a flu, today I had to go out .. I needed some fresh air and exercise.

So we went to Dortmund to “Zeche Zollern”, wich is a very nice coal mine.

Here some information about this mine from wikipedia (Wikipedia):

The Zeche Zollern II/IV (translated: Zollern II/IV Colliery) is located in the northwestern suburb of Bövinghausen of DortmundGermany. The Gelsenkirchener Bergwerks-AG projected Zollern in 1898 as a model colliery.

You really should visit this mine – it’s very nice and cosy.
