The Kings of England had many palaces, both within and without the City. Their principal palace from King Cnut to King Henry VIII. was the “King’s House” of Westminster. Within the City itself was first and foremost the Citadel, Castle, Palace, and Prison, called the Tower of London. Baynard’s Castle was held successively by the Baynards, who lost it in 1111, by a son of Gilbert, Earl of Clare, and his heirs until 1213, when the then holder, Robert FitzWalter, being on the side of the Barons, the King seized and destroyed the place. Afterwards, however, he permitted the owner to restore it. This was done imperfectly, for when the Dominicans removed from their quarters in Holborn to the place now called Blackfriars, they built their church and part of their house with the stones of Baynard’s Castle and the Tower of Montfichet. In 1428 Humphrey, Duke of Gloucester, built a house by the riverside to the east of the old castle, and apparently named it after the former Baynard’s Castle, just as at the present day we call a modern structure in Regent’s Park by the old and venerable name of St. Katherine’s by the Tower. A smaller Tower stood beside the first Baynard’s Castle, also on or without the wall, called Montfichet. Both places were intended by the Normans as strongholds, from which the City could be kept down, if necessary. On the building of the Dominican House, the Mayor of London, Gregory Rokesley, gave permission for the use of some of the stones by the Friars. The best of them had already been taken for the repair of St. Paul’s. A third Tower was built at the confluence of the Fleet and the Thames, by order of the King, upon the portion of wall south of Ludgate Hill. This tower is described by Stow as having been “large and magnificent and such as was fit for the reception of a king; and where Edward I. intended some time at his pleasure to lye.” He granted to the citizens a three years’ toll on goods brought into the City for sale, in order that they might build the wall so as to enclose the Dominicans’ house, and put up this tower at the angle. It stood until 1502, when John Shaw, Mayor, commanded it to be taken down. On the west bank of the Fleet, opposite to this Tower, was another, afterwards called Bridewell. Stow’s account of its early history has an air of uncertainty:—
