In reply to The Ivanator:
Hmm, England seems to have a great many 'exquisite climbs in grim holes'. Lucky you.
Surprised no-one's mentioned one that straddles the Welsh border:
Llanymynech Quarry . It's a very big and very grim hole, definitely in the 'in-yer-face' category.
Admittedly, the English part of the quarry is a bit less grim now that some recent clearance of the rapidly encroaching jungle has taken place, but pretty it is still not, while the neglected and largely unloved Welsh part is getting grimmer and more Jurassic-like by the day. Take your pick of the 3 star routes as there are three E2-E4 trad routes on Black Wall and four F7a clip ups on Nomad Wall.
Blind Faith (VS) is also probably worth 3 stars for the sheer improbability and audacity of the climbing rather than quality per se, although it once featured as a 'Climb of Quality' in Climber and Rambler mag in the late 1970s, presumably following an ascent where good judgement was badly clouded after a heavy session of alcohol or substance abuse. Not a route to comfortably solo; the route name itself is a bit of a give-away ....
