Take a trip down the north side of Bene't Street in the centre of the city of Cambridge in England and you'll notice a buzz of lunchtime drinkers and patrons enjoying a pint in a pub with some special history.
When you first walk into The Eagle pub, the first thing that you may notice is the seemingly dirty ceiling with its graffiti covered brown display. There are five rooms in this huge pub and the RAF bar was a regular haunt during the Second World War by Royal Air Force airmen who burned their markings into the ceiling with petrol lighters. They probably used each other's shoulders to reach the eight-foot high ceiling.
The beer garden at the front is overlooked by university rooms and lecture halls. Run now by Greene King Breweries, the land is now owned by by Corpus Christi College - one of the more ancient colleges of the University of Cambridge - founded in 1352.
Originally called The Eagle and Child the pub dropped the "Child" and rebuilt the RAF bar in the 19th century.
In 1953 when the university's Cavendish Laboratory was still located on Free School Lane the pub became hugely popular for a lunchtime tipple or two for the staff working at the university. It then became the place where Francis Crick and James Watson had "discovered the secret of life" after they had come up with their proposal for the structure of DNA.
Watson and Crick had proposed the double helix or spiral staircase structure of the DNA molecule.
For further reading on the Structure for Deoxyribose Nucleic Acid make sure you grab your pint of real ale and relive Watson and Crick's paper over a sumptuous ploughman's lunch or wild mushroom soup.
You never know you could be inspired with a life changing notion at this busy city centre pub.
