Enjoy climbing – with an industrial appeal

A historic industrial building, colourful bouldering walls of varying degrees of difficulty and courses for beginners, professionals and children, plus a cosy café – the Schlüsselstelle in Siegen’s Weidenau district is the bouldering hall that has it all.


Since December 2014, the former turnery of the Charlottental metal foundry has revolved around a special kind of climbing known as bouldering. This exciting struggle against gravity calls for agility, dynamism, balance, strength and the correct tactics. Beginners and children can join courses to learn from real professionals how to approach the tricky vertical movement challenge.
