The Outer Ward forms a strip of ground varying in breadth from 20 to 100 feet, its wall forming the scarp of the moat. It is defended by bastions to the north-east and north-west, which are 80 feet in diameter, that to the north-east being called the Brass Mount Battery, that to the north-west, Legge’s Mount, so named from George Legge, first Earl of Dartmouth, who was Master-General of Ordnance in the reign of Charles II. The Brass Mount probably derived its name from the cannon with which it was mounted. Between these bastions is a more modern one, called the North Bastion. These three bastions defend the north side of the fortress. Of the five towers which protected the Palace on the river front, the Byward and St Thomas’s Towers have already been described. There remain the Cradle, the Well, and the Develin Towers to notice. The Cradle Tower stands parallel with the Well Tower on the outer or curtain wall. It was through an archway in the Cradle Tower that the principal entrance from the river lay in former times. From the top of the tower a square-shaped turret rises on the western side. The Cradle Tower dates from the reign of Henry III., and prisoners were landed here as well as at Traitor’s Gate, entering the fortress over a drawbridge. Its upper chambers, which were in the form of the letter ⏉, are believed to have formed part of the Palace. The present tower is altogether modern, having been rebuilt from the foundations in 1878. The next tower on the curtain wall is the Well Tower, also entirely rebuilt. It is rectangular, and forms a portion of the curtain wall. Its basement lies below the level of the Inner Ward, and within it is a vaulted chamber 11 feet high by 14 feet wide, from which a well staircase leads to an upper room, and thence on to the rampart. The last of these towers at the eastern end of the fortress is the Develin Tower. In 1549 it was known as Galligman’s Tower, and in the plan of the Tower in 1597 it is called the “tower leading to the Inner Gate.” Formerly, it was used as a powder magazine. THE WHITE TOWER In the days of the Plantagenets, “La Tour Blanche” owed that appellation to its having been frequently whitewashed. The earliest of these whitewashings took place in the reign of Edward III., since whose reign it is impossible to guess how often the grim old building has been externally whitened. In an illumination taken from an old French MS. made in the reign of Henry V., and preserved in the Harleian collection in the British Museum, of the poems of Charles of Orleans, the vivid whiteness of the old Norman White Tower stands out in bold relief surrounded by the dark towers and walls of the fortress. And after half-a-thousand years of London grime and smoke, the White Tower remains the same “Tour Blanche” of the days of the Plantagenets.
