Built by route setters
Crux opened in 2016 in an old cutlery works in Kelham Island, Sheffield, started by two route setters who wanted a wall where beginners and strong climbers share the same mats.

Nadia Okafor and Tom Hartley met setting routes in Sheffield gyms, then found the cutlery works and spent a summer turning it into a bouldering centre. We keep their hands-on approach: every wall, every problem and every induction is run by people who climb.
There are around 250 problems on 1,100 square metres of wall, with a new set every week. Gritstone is half an hour away, so the gear shop at the front desk stocks what Sheffield climbers actually use inside and out.
First-timers and strong climbers climb side by side, on the same problems and the same mats.
We reset part of the wall every Tuesday and Thursday, so there is always something new to try.
