Origin of the name
There are four main theories as to the meaning of the name.
- It may mark the boundary between the central university area of Cambridge (referred to as the "reality bubble") and the "real world" of non-academic locals living beyond. One is warned to check one's notions of reality before passing. For students at Cambridge, who walk out to Mill Road across Parker's piece for an evening in the "real world", usually including a visit to one of Mill Road's selection of pubs, the lamppost marks the end of the "reality holiday" as they walk back to central Cambridge – back into "the bubble".
- The name arose because the lamppost forms a useful landmark for people crossing the park at night – perhaps inebriated or in the fog – since it is the only light for over a hundred metres.
- When drunk, students and the general public are reminded to check they are able to walk like a sober person before passing the police station at the edge of Parker's Piece.
- The post being situated in the middle of two walking paths that intersect, anyone walking, or cycling in the fog, whilst not tuned in to "reality" will probably collide with the lamppost, hence "reality checkpoint".
The lamppost dates from about 1860 and is made of cast iron by the Sun Foundry of George Smith and Company in Glasgow. It stands on a square-section plinth with waterleaf decoration on the top edges. The base of the shaft of circular section is encircled with four intertwined heraldric dolphins. The shaft carries four lamp holders by means of scrolled wrought-iron stays. Presumably it was originally lit by gas and subsequently converted to electricity. It is said be the oldest electrical lamppost in Cambridge.
The post above the dolphins was torn down by American soldiers celebrating VJ Day, the end of the war with Japan. In 1947 the lamppost was repaired by a local metalworks firm, George Lister & Sons, Cambridge. The work was done by foreman Sam Mason, assisted by a young apprentice, Tony Challis, who did the scrollwork at the top of the lamppost. Challis still lives in Cambridgeshire, and is also responsible for the ornate railings found at Granchester Meadows.
One report claims that the name was first painted on the lamppost in the early 1970s by students from the Cambridgeshire College of Arts and Technology (now Anglia Ruskin University) under the guidance of one of their teachers.
The name has been repeatedly repainted following its removal by Cambridge City Council or obliteration by graffiti. For the first half of 1998 the lamppost carried an unofficial plaque bearing its name, until removed by the council.
Comedian Ben Miller featured the lamppost in his BBC Two physics documentary "What Is One Degree?" for the science series Horizon. At that time the lamppost had the words "Reality Checkpoint" scratched into its paintwork in at least two places.
