Lensfield Road (part of the A603) is in southeast central Cambridge. It runs between the junction of Trumpington Street and Trumpington Road to the west and the junction of Regent Street and Hills Road to the west.
On the south side of the road are the Scott Polar Research Institute, St Albans Primary School and the University of Cambridge's Department of Chemistry. On the corner with Hills Road is Our Lady and the English Martyrs Church.
To the north between Tennis Court Road and Regent Street is Downing College, which owns many properties on the road.
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.
