A forgotten door built for festivities surrounding the coronation of King Charles II in 1661 has been rediscovered in the Houses of Parliament. 

The door, hidden behind panelling in cloister formerly used as offices by the Parliamentary Labour Party, was originally constructed to allow guests at the coronation to make their way to his celebratory banquet in Westminster Hall.

It was subsequently used by the likes of Robert Walpole, often referred to as the first Prime Minister as well as architect-led rivals Charles James Fox and William Pitt the Younger, and diarist Samuel Pepys.

The door and passageway behind it survived the fire which destroyed much of the Palace of Westminster in 1834 but it was thought the passage had been filled in during restoration works after the Palace of Westminster was bombed in World War II.

Liz Hallam Smith, an historical consultant from the University of York who is working with the team undertaking the renovations, said they were trawling through “10,000 uncatalogued documents relating to the palace at the Historic England Archives in Swindon, when we found plans for the doorway in the cloister behind Westminster Hall”.

“As we looked at the paneling closely, we realised there was a tiny brass key-hole that no-one had really noticed before, believing it might just be an electricity cupboard,” she said. “Once a key was made for it, the paneling opened up like a door into this secret entrance.”

In the small room behind the door, the team discovered the original hinges for two wooden doors some three-and-a-half meters high that would have opened into Westminster Hall. They also found graffiti, scribbled in pencil by bricklayers who worked on the restoration of the palace in 1851 following the 1834 fire.

One section reads “This room was enclosed by Tom Porter who was very fond of Ould Ale” and another, “These masons were employed refacing these groines…[ie repairing the cloister] August 11th 1851 Real Democrats”, the latter a reference suggesting the men were part of the working class male suffrage Chartist movement.

Sir Lindsay Hoyle, the House of Commons Speaker, described the find as “part of our parliamentary history”: “To think that this walkway has been used by so many important people over the centuries is incredible.”
