On Friday 5th April the coffin of Queen Elizabeth The Queen Mother was carried in a ceremonial procession to Westminster Hall. It Lay-in-State until the morning of Tuesday 9th April.

Westminster Hall is the oldest surviving building of the ancient Palace of Westminster which, from the reign of Edward the Confessor (1042-66) to the early years of Henry VIII (1509-47), was the principal residence of the Kings of England. The Hall was built to its present dimensions (240 feet by 69 feet) by William Rufus in 1097-99.

At first the Hall was an aisled building, with two rows of columns supporting a lower, lighter and simpler roof, an arrangement which continued for 300 years. Between 1394 and 1399, in the reign of Richard II, the Hall was transformed, its Norman walls being heightened and buttressed to enable them to carry the weight of a great new roof of English oak, designed to cover the building in a single span, without the need for supporting columns.

This roof, seen today, is the greatest surviving achievement of medieval English timberwork. It was the creation of Hugh Herland, the King's master carpenter. It is constructed on the cantilever or 'hammerbeam' principle, and is the earliest as well as the most extensive roof of this type in existence.

The roof lantern, now glazed, was the large opening through which the smoke from the medieval fires was expelled. The windows and the new stonework were by Henry Yevele, the master mason.

Since the roof was completed in 1399, it has been repaired in 1819, in 1913 and again in 1945, after slight damage by incendiary bombs during the war.

The derivation of judicial authority from the person of the King led to the use of the Hall for holding the King's courts. By the 14th century the north-west, south-east and south-west corners had become established meeting places of Courts of Common Pleas, King's Bench and Chancery respectively.

The normal use of the Hall for dispensing justice only came to an end in 1882 when the Courts of Justice moved to the Strand. The remaining space within the Hall along the walls was occupied by shops and stalls.

This general arrangement was from time to time interrupted for great public and parliamentary occasions. Coronation banquets took place in the Hall from at least 1170, the last being that of King George IV in 1821.

In the 20th century luncheons were also held here for representatives of Commonwealth Parliaments on the occasion of the Coronation of the Sovereign. The Hall has also witnessed many state trials and impeachments, such as those of Sir Thomas More in 1535, of Guy Fawkes in 1606, and of Charles I in 1649.

The Hall has continued to be used for such solemn ceremonial occasions as the Lying-in-State of members of the Royal family, including King George VI who lay in state for three days and four nights in 1952, and two great commoners, William Gladstone and Winston Churchill.

The Hall has also been the setting for a number of parliamentary occasions, notably the presentation of Addresses by both Houses of Parliament to the Sovereign.

Addresses were presented in 1965 to mark the seventh centenary of the summoning, to the Hall, of the Parliament of Simon de Montfort, and in 1977 and 2002 to celebrate the 25th and 50th anniversaries of the accession to the Throne of Her Majesty The Queen.
