Lying between the Palace of Westminster and the Westminster Abbey, this unremarkable-looking public space was once the scene of some of England's bloodiest executions - perhaps most famously the setting of the execution of Guy Fawkes and his co-conspirators of the Gunpowder Plot.
Today, most of the yard is behind concrete barriers for much of the year as a security measure, and used as a car park for Parliamentary business. At its centre is an impressive statue of Richard the Lionheart on horseback. Access to the Western end of the park remains open to the public however
At one time, the square was actually surrounded by residential houses, only one of which now remains standing, as part of the Parliamentary estate.
