House of Lords Chamber was occupied by the House of Commons, whose chamber had been destroyed by the Blitz in 1941. Royal Gallery Immediately north of the Robing Room is the Royal Gallery. At , it is one of the largest rooms in the Palace. Its main purpose is to serve as the stage of the royal procession at State Openings of Parliament, which the audience watch from temporary tiered seating on both sides of the route. It has also been used on occasion by visiting statesmen from abroad when addressing both Houses of Parliament, as well as for receptions in honour of foreign dignitaries, and more regularly for the Lord Chancellor's Breakfast; in the past it was the theatre of several trials of peers by the House of Lords. Documents from the Parliamentary Archives are on display in the Royal Gallery (including a facsimile of Charles I's death warrant), and the tables and seating offer a workspace for members of the Lords that is conveniently close to their debating chamber. The decorative scheme of the Royal Gallery was meant to display important moments in British military history, and the walls are decorated by two large paintings by Daniel Maclise, each measuring : The Death of Nelson (depicting Lord Nelson's demise at the Battle of Trafalgar in 1805) and The Meeting of Wellington and Blücher after the Battle of Waterloo (showing the Duke of Wellington meeting Gebhard Leberecht von Blücher at the Battle of Waterloo in 1815). The murals deteriorated rapidly after their completion due to a range of factors, most importantly atmospheric pollution, and today they are almost monochrome, although a finished study of The Death of Nelson in better condition hangs in the Walker Art Gallery, Liverpool. The rest of the planned frescos were cancelled, and the walls are filled with portraits of kings and queens from George I onwards. Another decorative element with military undertones are the eight statues of gilded Caen stone that flank the three doorways and the bay window of the Gallery, sculpted by John Birnie Philip. Each depicts a monarch during whose reign a key battle or war took place. They are: Alfred the Great and William the Conqueror; Richard I and Edward III; Henry V and Elizabeth I; William III and Anne. The panelled ceiling, above the floor, features Tudor roses and lions, and the stained-glass windows show the coats of arms
