This year’s season of association’s promotional activity slowly reached its end. The second and final event of this type is past.

On 22^nd and 23^rd May 2015 we took part in the 7^th International Fairs of Industrial Heritage and Underground Tourism. We would like to thank to all those who has visited our stand. We would like to express our gratitude to the organizers of the fairs – the City of Zabrze – for renting us the stand free of charge and for a warm reception.
