This week's Friday Night Video is an in-depth look at the evolution of indoor bouldering walls by YouTuber Hannah Morris. As the discipline soars in popularity, we are in a golden age for indoor bouldering.

There are a staggering 20,000+ climbing gyms worldwide and 38 bouldering gyms in London alone - with new facilities opening every year.

Hannah explores how both the physical spaces of bouldering gyms and the communities that form in them have changed by visiting the oldest and newest dedicated centres in the UK: the Mile End Climbing Wall and The Climbing Hangar Edinburgh, built in 1980 and 2024 respectively.
