Why a Railway Arch?
The vaulted ceiling creates the height needed for climbing routes and bouldering problems. The curved shape adds interest to route-setting. Central London locations are accessible to the urban climbing market. And the industrial aesthetic appeals to the climbing community. Arches can accommodate both bouldering (lower, no ropes) and top-rope climbing (taller arches).
