<P> Westminster Hall has served numerous functions . Until the 19th century, it was primarily used for judicial purposes, housing three of the most important courts in the land: the Court of King's Bench, the Court of Common Pleas and the Court of Chancery . In 1875, these courts were amalgamated into the High Court of Justice, which continued to meet in Westminster Hall until it moved to the Royal Courts of Justice in 1882 . In addition to regular courts, Westminster Hall also housed important trials, including impeachment trials and the state trials of King Charles I at the end of the English Civil War, William Wallace, Thomas More, Cardinal John Fisher, Guy Fawkes, the Earl of Strafford, the rebel Scottish lords of the 1715 and 1745 uprisings, and Warren Hastings . The St Stephen's Porch end of the Hall displays under the stained glass window the Parliamentary War Memorial listing on eight panels the names of Members and staff of both Houses Parliament and their sons killed serving in the First World War; the window itself, installed in 1952, commemorates members and staff of both Houses who died in the Second World War . In 2012, a new stained glass window commemorating Elizabeth II's diamond jubilee was installed opposite this window, at the other end of the hall . </P> <P> Westminster Hall has also served ceremonial functions . From the twelfth century to the nineteenth, coronation banquets honouring new monarchs were held here . The last coronation banquet was that of King George IV, held in 1821; his successor, William IV, abandoned the idea because he deemed it too expensive . The Hall has been used for lyings - in - state during state and ceremonial funerals . Such an honour is usually reserved for the Sovereign and for their consorts; the only non-royals to receive it in the twentieth century were Frederick Sleigh Roberts, 1st Earl Roberts (1914) and Winston Churchill (1965). The most recent lying - in - state was that of Queen Elizabeth The Queen Mother in 2002 . </P> <P> The two Houses have presented ceremonial Addresses to the Crown in Westminster Hall on important public occasions . For example, Addresses were presented at Elizabeth II's Silver Jubilee (1977), Golden Jubilee (2002) and Diamond Jubilee (2012), the 300th anniversary of the Glorious Revolution (1988), and the fiftieth anniversary of the end of the Second World War (1995). </P> <P> It is considered a rare privilege for a foreign leader to be allowed to address both houses in Westminster Hall . Since the Second World War the only leaders to have done so have been French president Charles de Gaulle in 1960, South African president Nelson Mandela in 1996, Pope Benedict XVI in 2010, U.S. president Barack Obama in 2011 and Burmese opposition leader Aung San Suu Kyi in 2012 . President Obama was the first ever US President to be allowed to use the Hall for an address to Parliament and Aung San Suu Kyi was the first non-head of state to be given the accolade of addressing MPs and peers in Westminster Hall . </P>
