Although there can be no doubt that here was a gate in the Roman period, we have little or no record of its early history. One of its earlier names was Chamberlain's Gate. The 'new' gate was erected in the reign of Henry I., and in a Pipe Roll of 1188 it is mentioned as a prison. In 1414 the prison was in such a loathsome condition that the keeper and sixty-four of the prisoners died of the prison plague. In consequence of this it was decided to rebuild the gate. Richard Whittington was the moving spirit in this rebuilding, and it is supposed that he paid the expenses. In the course of excavations made in 1874-1875 for the improvement of the western end of Newgate Street, the massive foundations of Whittington's gate were discovered several feet below the present roadway. The wall passed north through the precincts of Christ Church (Christ's Hospital), formerly occupied by the Grey Friars (or Franciscans). The town ditch, which was outside the walls, and arched over about the year 1553, ran through the Hospital grounds. The wall then turned round to the north of Newgate Street, and passed into St. Martin's-le-Grand, where, in 1889, the foundations of several houses on the west side were exposed while the excavations for the latest addition to the General Post-Office were being proceeded with. The great bell of the Collegiate Church of St. Martin's tolled the curfew hour when all the gates of the city were to be shut. The great gates were shut at the first stroke of the bell at St. Martin's and the wickets opened; at the last stroke the wickets were to be closed, and not to be opened afterward that night unless by special precept of the Mayor. The ringing of the curfew of St. Martin's was to be the signal for the ringing 'at every parish church, so that they begin together and end together.'[18] In an Ordinance (37 Edward III., 1363) the bell at the Church of our Lady at Bow was substituted for that at St. Martin's. Outside the walls were Smithfield, where the tournaments were held, and Giltspur Street, where the knights bought their spears, and armour might be repaired when tournaments were going on. Within the gate were the Grey Friars, Stinking Lane (now King Edward Street), and the Butchers' Shambles in Newgate Street.
