This year's light display was on the southern wing seen in TL4557 : Fitzwilliam Museum. The central window was a bit of a snag for most of the projected slides, meaning this coloration of the architecture was probably the most effective moment.
This is Fitzwilliam Street, in Little St Mary's parish. Probably its most famous resident was Charles Darwin, who lodged here while studying at Christ's College (1828-1831). Darwin's mentor, the Professor of Botany John Stevens Henslow, was a curate at Little St Mary's.
