St Andrew's Street is a major street in central Cambridge. It runs between Sidney Street, at the junction with Hobson Street, to the northwest and Regent Street to the southeast. Downing Street leads off to the west.
On the northeastern side of the street are Christ's College and Emmanuel College. On the southwestern side are St Andrew the Great church and St Andrew's Street Baptist Church.
Reality Checkpoint - so called because it supposedly marks the spot, halfway across Parker's Piece, where the bubble of Cambridge University ends and the "real world" of Cambridge city begins. I believe there used to be a plaque inscribed "reality checkpoint" on the lamp-post, but that is long gone and the words are now rather crudely scratched into the paintwork.
