Stink pipes or Stench pipes are found above sewers and are there to vent off gases from the sewers below. Most stink pipes date from the Victorian period.

Parker's Piece is a 25-acre flat and roughly square green common located near the centre of Cambridge and is now regarded as the birthplace of the rules of Association Football. The two main walking and cycling paths across it run diagonally, and the single lamp-post at the junction is colloquially known as Reality Checkpoint TL4558 : Reality Checkpoint, Parker's Piece. The area is bounded by Park Terrace, Parkside, Gonville Place, and Regent Terrace. The Cambridge University Football Club Laws were first used on Parker's Piece and adopted by the Football Association in 1863.
The grass is well manicured and it is known today chiefly as a spot for picnics and games of football and cricket, and serves as the games field for nearby Parkside Community College.
