During the Roman period, the Guildhall was the site of an amphitheatre, the largest in Britannia, partial remains of which are on public display in the basement of Guildhall Art Gallery and the outline of whose arena is marked with a black circle on the paving of the courtyard in front of the hall. Indeed, the siting of the Saxon Guildhall here was probably due to the amphitheatre's remains. Excavations by Museum of London Archaeology at the entrance to Guildhall Yard exposed remains of the great 13th-century gatehouse built directly over the southern entrance to the Roman amphitheatre, which raises the possibility that enough of the Roman structure survived to influence the siting not only of the gatehouse and Guildhall itself but also of the church of St Lawrence Jewry whose strange alignment may shadow the elliptical form of the amphitheatre beneath. The first documentary reference to a London Guildhall is dated 1128. Legend describes the Guildhall site as being the location of the palace of Brutus of Troy, who according to Geoffrey of Monmouth's Historia Regum Britanniae is said to have founded a city on the banks of the River Thames, known as Troia Nova, or New Troy. The great hall is believed to be on a site of an earlier Guildhall. Possible evidence for this derivation may be in a reference to John Parker, the sergeant of "Camera Guyhalde", London, in 1396.
Current building
The current building began construction in 1411 and completed in 1440. Trials at the Guildhall have included those of Anne Askew, Thomas Cranmer and Lady Jane Grey as well as Henry Garnet. The 1783 hearing of the infamous Zong case, the outcome of which focused public outrage about the transatlantic slave trade, also took place at Guildhall. On 16 November 1848, the pianist Frédéric Chopin made his last public appearance on a concert platform there. design was not retained. The Great Hall did not completely escape damage in the Great Fire of London in 1666; it was partially restored in 1670. The present grand entrance, in "Hindoostani Gothic", was added in 1788 by George Dance. A more extensive restoration than that in 1670 was completed in 1866 by the City of London architect Sir Horace Jones, who added a new timber roof in close keeping with the original hammerbeam ceiling. This replacement was destroyed during the Second Great Fire of Londonon the night of 29/30 December 1940, the result of a Luftwaffe fire-raid. It was replaced in 1954 during works designed by Sir Giles Gilbert Scott, though the original hammerbeam design was not retained. The marathon route of the 2012 Summer Olympics passed through Guildhall Yard.
Present use
The day-to-day administration of the City of London Corporation is now conducted from modern buildings immediately to the north of Guildhall, but Guildhall itself and the adjacent historic interiors are still used for official functions, and it is open to the public during the annual London Open House weekend. Guildhall Art Gallery was added to the complex in the 1990s. Guildhall Library, a public reference library with specialist collections on London, which include material from the 11th century onwards, is also housed in the complex.
Two giants, Gog and Magog, are associated with Guildhall. Legend has it that the two giants were defeated by Brutus and chained to the gates of his palace on the site of Guildhall. Early carvings of Gog and Magog were destroyed in Guildhall during the Great Fire of London. They were replaced in 1708 by a large pair of wooden statues carved by Captain Richard Saunders. These giants, on whom the current versions are based, lasted for more than two hundred years before they were destroyed in the Blitz. They, in turn, were replaced by a new pair carved by David Evans in 1953 and given to the City of London by Alderman Sir George Wilkinson, who had been Lord Mayor in 1940 at the time of the destruction of the previous versions.
Functions
Guildhall hosts many events throughout the year, the most notable one being the Lord Mayor's Banquet, which is held in honour of the immediate-past Lord Mayor and is the first to be hosted by the new Lord Mayor of the City of London. In keeping with tradition, it is at this banquet that the Prime Minister makes a major world affairs speech. One of the last acts of the outgoing Lord Mayor is to present prizes at the City of London School prize day at Guildhall. Other events include those of various law firms, award evenings for the Wine and Spirit Education Trust, and the banquet for the International Wine and Spirit Competition. The Worshipful Company of Carmen holds its cart-marking ceremony in the courtyard each July.
Members Bar
The Members Bar in the Guildhall is a highly subsidised facility for members of the Court of Common Council and the Court of Aldermen. However, access to the facilities becomes a privilege for life even after an individual is no longer a member of either of these courts. Members can also entertain guests there. With spirits available for as little as 60p in October 2017, it is substantially cheaper than any other bar in the City of London. The bar is subsidised from the City's Cash, a sovereign wealth fund.
