The quarry that we see today was first begun in the 16th century. Excavation was continued and reached a peak in the 19th century. Quarrying ceased in 1893. During the second world war the quarry was used as a target practice range which is how Pisa Wall got its distinctive round pockets. This works in direct contrast to Lady Jane Wall which is more slabby and features crimps on the left hand side and breaks on the right hand side.

It is hard to say when climbing began in the quarry but the earliest FA I have been able to find is "Dateline (E2 5c) FA Rick Newcombe and Geoff Ashton, 1960s". It is certain that much climbing was done prior to this as there are many easier routes available.

Climbing continued and soon Pex Hill became the training ground for a young Phil Davidson and Joe Healey. Both went on to great things with Phil completing the first solo ascents of Cockblock and Right Wall.

Climbing is still of an excellent standard at Pex despite the recent wire brushing of Breakaway and the chipping on Lady Jane Wall.
