King Henry V., in 1415--the year of his famous victory at Agincourt--granted the City free passage for four boats by water, and as many carts by land, to bring lime, ragstone, and freestone for the work at Guildhall. Private citizens also came forward with contributions. The executors of Sir Richard Whittington, in 1422-3, gave two sums of L60 and L15 for paving the hall with Purbeck stone, and glazed some of the windows, placing in each the arms of Whittington. The rest of the windows in the hall and many of those in its various courts were glazed by various aldermen. So much of this ancient glass as survived the iconoclasm of the Commonwealth period was swept away by the Great Fire. The two handsome louvres which formed such conspicuous objects on the roof of the building were given by Alderman Sir William Hariot during his mayoralty in 1481. The mayor's chamber, council chamber, and several rooms above were built in 1425-6. An important part of the building was still wanting, for the mayors could not keep their feasts at the Guildhall until the time of Sir John Shaa. Under his leadership, and by the help of the Fellowships of the City, wealthy widows, and other well-disposed persons, the kitchens and other necessary offices were completed for use at his mayoralty feast in 1501. Since that year these famous banquets, which had till then been held in Merchant Taylors' Hall, or Grocers' Hall, have regularly taken place at the Guildhall. On Tuesday, 4th September, 1666, in the course of the Great Fire, the Guildhall was ablaze, and its oak roof entirely destroyed. Vincent describes its appearance in his little book, _God's Terrible Voice to the City_: "That night the sight of Guildhall was a fearfull spectacle, which stood the whole body of it for several hours together, after the fire had taken it without flames (I suppose because the timber was such solid oake) in a bright shining coale as if it had been a palace of gold or a great building of burnished brass." After the Fire the original open roof was not rebuilt, but the walls were raised an additional storey, the ceiling covering this being flat and square panelled; eight circular windows on each side were added. This poor substitute for a roof was built, as Elmes states, "in haste and for immediate use, and evidently a temporary covering." It lasted, nevertheless, nearly two hundred years, until in 1861 the plans for a new open roof corresponding with the original design of the Guildhall were approved by the Corporation. The dimensions of this magnificent building are 152 feet in length, 49 feet 6 inches in width, and 89 feet in height, from the pavement to the ridge of the roof.
