This week saw a fair amount of activity by Cambridge's favourite secret club. Santa hats have been appearing on various parts of the University's architecture - most notably on all four pinnacles of King's College Chapel as pictured (pic thanks to avaragado, click through for more and follow him on Twitter.) The Santa hat deluge is a pretty regular occurrence at this time of year; followers of this column will know that the Night Climbers have been a part of Cambridge subculture for over a hundred years definitely, and probably a lot longer (on Gunning's Balcony, St John's College, there's an inscription carved by pen-knife: PETRUS GUNNING ELIENSIS, HUJUS COLL : ALUMNUS Feb: 19th, 1734).
Those interested can read a free pdf on the history of Night Climbing below (and on the Oleander website.)
