The porch was known as the Guildhall Gate, and there was a lower gate which was probably situated in a line with the Church of St. Lawrence Jewry, in Gresham Street.
The crypt is one of the best of the few mediæval examples remaining in London. It forms the eastern portion of the sub-structure of the hall, and is 76 feet by 45-1/4, with an average height of 13 feet 7 inches. It is divided into three equal portions by clustered columns of Purbeck marble, from which spring the stone-ribbed groins of the vaulting. The bosses at the intersections are all carved with devices of the usual mediæval character, and include the arms assigned to the Confessor and those of the See and City of London.
Of these crypts--a beautiful feature of ancient architecture in which London formerly abounded--the great part have disappeared. There are those of the Church of St. Bartholomew the Great, Smithfield; Bow Church, Cheapside (used for burial purposes); Etheldreda's Chapel, Ely Place; the Priory Church of St. John, Clerkenwell; Lambeth Palace; Merchant Taylors' Hall; and St. Stephen's Chapel, Westminster. Several fine examples have been destroyed within quite recent times, including the crypt or Lower Chapel of Old London Bridge, Gerard's Hall crypt in Basing Lane, and that under the Manor of the Rose in Lawrence Pountney Hill, the two latter buildings being fine examples of the houses of distinguished citizens. To this tale of destruction must be added the crypts of Lamb's Chapel in Monkwell Street, Leathersellers' Hall, St. Martin's-le-Grand, and St. Michael, Aldgate.
The Guildhall was, in a very real sense, the centre of civic government. In early times the Mayor, Aldermen, and Sheriffs were practically the King's servants, and responsible to him at their personal peril for the good and quiet government of the city. For this purpose an adequate authority was conferred upon the civic magnates over the life and liberty of each individual citizen. The city was divided into twenty-five wards, over each of which an Alderman presided, who was responsible for its good government to the Mayor. Severe was the punishment for an insult offered to one of these dignitaries. In 1388, Richard Bole, a butcher, for insulting William Wotton, alderman of Dowgate, was, by order of the Mayor, imprisoned in Newgate, and ordered, as a penance, to carry a lighted torch, with head uncovered and bare legs and feet, from his stall in St. Nicholas' Shambles to the Chapel of the Guildhall. Rough-and-ready justice was administered by the Mayor and his brethren, the Aldermen. In 1319, William Spertyng, who was found guilty of exposing for sale at the shambles two putrid carcases, was sentenced to be put in the pillory, and to have the carcases burnt beneath him. A vintner named John Penrose, convicted in 1364 of selling bad wine, was ordered to drink a draught of the "same wine which he sold to the people," the remainder to be poured on his head, and he to forswear the calling of a vintner in the City of London for ever. For giving short weight, in 1377, two charcoal dealers were set in the stocks on Cornhill, whilst six of their badly filled sacks were burnt beside them. A baker, for selling bread of light weight, was dragged through the city on a hurdle with the offending loaf hung about his neck. An illustration of this punishment is given in an ancient book belonging to the city records, known as the "Liber de assisa panis." Another punishment which must have been sufficiently deterrent was that of whipping at the cart's tail for petty larceny and other minor offences.
