Lions were a part of the royal state, and lodged in the Tower bulwark, in the reign of Henry I. The Emperor Frederick, in 1235, sent Henry II. three leopards; and, in 1252, Henry III. received a white bear from Norway, for whose sustenance, with his keeper, the sheriffs of London provided fourpence daily, with a muzzle and iron chain, to keep him when “extra aquam,” and a stout cord to hold him when a-fishing in the Thames. In 1254, Louis of France sent the king an elephant. He was brought from Sandwich to the Tower, where the sheriffs were to build him a strong and suitable house, 40 feet by 20 feet, and to support him and his keeper. Edward I. and Edward II. kept lions here. At a time when the allowance for an esquire was one penny per day, a lion had a quarter of mutton and three-halfpence for the keeper; and, afterwards, sixpence was the lion’s allowance; the same for a leopard, and three-halfpence for the keeper. In 16 Edward III., there were a lion and a lioness, a leopard, and two cat-lions. In 1543, the Duke of Najara saw here four large and fierce lions, and two leopards. The menagerie was finally closed about the year 1830. Its establishment on this particular spot was probably due to Henry III. The whole outward space was, in 1597, called the Bulwark, and sometimes the Spur-yard. HISTORY. Having decided to build an “Arx Palatina,” and having some years’ experience of the value of the proposed site as a temporary camp, the Conqueror at length determined to erect a regular castle, and entrusted the work to Gundulf, a monk of Bec, who, in 1077, soon after his arrival in England, was consecrated Bishop of Rochester. Gundulf brought with him from Normandy some reputation as an architect, which vocation he pursued in this country. Rochester Keep, that strong but graceful tower, placed so judiciously above the ancient passage of the Medway, and long attributed to the bishop, is now known to be of later date; and the only existing buildings, besides the White Tower, which can safely be attributed to him, are the north tower of Rochester Cathedral, parts of the old crypt, and perhaps a small part of its west front; also the very perfect and unaltered shell of Malling Keep, known as St. Leonard’s Tower; possibly the broad, massive tower of the adjacent church, and, it may be, the Norman portions of that of Dartford. These remains, however, the White Tower, and the testimony of many generations, may be regarded as sufficient for the confirmation of his fame.
