"Within the walls of this fortress are several streets. The principal buildings which it contains are, the White Tower, the ancient chapel, the Ordnance-office, the Record-office, the Jewel-office, the Horse Armoury, the grand Storehouse, and the Small Armoury, besides the houses belonging to the constables and to other officers, the barracks for the garrison, and two suttling-houses, commonly used by the soldiers. "The principal entrance to the Tower is toward the west. It consists of two gates on the outside of the ditch, a stone bridge built over the ditch, and a gate in the inside. These gates are opened every morning with the following ceremony: the yeoman-porter, with a sergeant and six men, goes to the governor's house for the keys. Having received them, he proceeds to the innermost gate, and passing that, it is again shut. He then opens the three outermost gates, at each of which the guards rest their firelocks while the keys pass and repass. On his return to the innermost gate he calls to the warders on duty to take the Queen's keys, when they open the gate, and the keys are placed in the warders' hall. At night the same formality is used in shutting the gates; and as the yeoman-porter with his guard is returning with the keys to the governor's house, the main-guard, which, with its officers, is under arms, challenges him with 'Who comes there?' he answers, 'The keys,' and the challenger replies, 'Pass, keys.' The guards, by order, rest their firelocks, and the yeoman-porter says 'God save the Queen,' the soldiers all answering, 'Amen.' The bearer of the keys then proceeds to the governor's house, and there leaves them. After they are deposited with the governor, no person can enter or leave the Tower without the watchword for the night. If any person obtains permission to pass, the yeoman-porter attends, and the same ceremony is repeated. "The Tower is governed by its Constable, at present the Duke of Wellington; at coronations and other state ceremonies this officer has the custody of the crown and other regalia. Under him is a lieutenant, deputy-lieutenant, commonly called governor, fort-major, gentleman-porter, yeoman-porter, gentleman-gaoler, four quarter gunners, and forty warders. The warders' uniform is the same as that of the yeomen of the Queen's guards. "The Tower is still used as a state prison, and, in general, the prisoners are confined in the warders' houses; but, by application to the Privy Council, they are usually permitted to walk on the inner platform during part of the day, accompanied by a warder.
