Henry I was the earliest King apparently to use the Tower as a State prison. He shut up Ralph Flambard, Bishop of Durham, in the White Tower on the charge of illegally raising funds to build the very fortress. Probably the imprisonment was a sop to public opinion, for the Bishop was hated for his exactions. He escaped, however; got possession of a rope which had been hidden in a wine cask, invited his keepers to supper and made them drunk; then fastening the rope to a window bar he let himself down. A swift horse which some friends had provided for him carried him to the coast, and he went over to Normandy, where he was cordially received by Duke Robert. But after the battle of Tenchebrai had destroyed all the hopes of the latter, King Henry welcomed the overtures which Flambard made to him, and restored him to his see at Durham, where he afterwards achieved his beautiful architectural works. The Tower was from that time onwards a Royal Palace, as was Westminster in the West. We catch incidents of residence in two or three reigns, but they are few. It is noted by one chronicler that during the contest between Stephen and Matilda, Stephen broke through the older custom and kept the Pentecost festival in the Tower instead of at Westminster. One fact comes out clear enough. Some of the Norman Kings kept wild beasts; Henry I had some lions and leopards at his palace at Woodstock. Frederick II of Germany sent three leopards as a present to Henry III, and they were placed in the Tower, where were already some lions, an elephant, and a bear, probably other beasts as well. There is an old account of the arrival of an elephant at Dover, and the amazement of the people as it was led up to London. Amid all its vicissitudes the Tower remained a royal menagerie until 1834. The Sheriff of London was ordered in 1252 to pay fourpence a day for the keep of the bear, as well as to provide a muzzle and chain for him when he was set to catch fish in the Thames. All through the Plantagenet days the beasts had food provided at the cost of 6_d._ a day. Their keeper was a Court official, styled “The Master of the King’s bears and apes.” The bears dwelt in a circular pit, like that in the main street of Berne to-day. It was situated where the ticket office and refreshment rooms are now. In the days of James I the bears were baited for the brutal amusement of the privileged. In the reign of Queen Elizabeth a German tourist named Hentzner saw here “a great variety of creatures, viz. three lionesses, one lion of great size called Edward VI, from his having been born in that reign, a tiger, a lynx, a wolf excessively old, a porcupine, and an eagle. All these creatures are kept in a remote place, fitted up for the purpose with wooden lattices at the Queen’s expense.” All through our literature there are references from time to time to the Tower menagerie. The “Lion Gate” was so called from its proximity to this.
