The Climbing Gym for Bouldering O’bloc in Ostermundigen has been chosen by Lignum – among 17 other recent projects – to feature in the journal « Le bois, allié du sport. Des écrins de performances ». Built by Bauart in 2015, the new construction blends harmoniously with its surroundings and its vertical deployment is the only visible clue to suggest that it conceals an impressive 18-meter-high climbing wall that is unique in Switzerland.
