Excalibur Climbing Wall, Groningen, The Netherlands

Some grips are formed to mimic the conditions of outdoor rock, including some that are oversized and can have other grips bolted onto them.
History
The concept of the artificial climbing wall began in the UK. The first wall was created in 1964 at Leeds University by Don Robinson, a lecturer in Physical Education and founder of DR Climbing Walls, by inserting pieces of rock into a corridor wall. The first commercial wall was built in Sheffield, traditionally England's centre for climbing due to its proximity to the Peak District.
