The "Yeomen of the Guard," a corps of forty-eight warders, who are meritorious soldiers, dressed in the uniform of Henry VIII.'s reign on state occasions, and at other times wearing black velvet hats and dark-blue tunics, have charge of the exhibition of the Tower. The entrance is in a small building on the western side, where years ago the lions were kept, though they have since been all sent to the London Zoological Garden. From this originated the phrase "going to see the lions." At the centre of the river-front is the "Traitor's Gate," through which persons charged with high treason were formerly taken into the Tower. It is a square building erected over the moat, and now contains a steam pumping-engine. Opposite it is the Bloody Tower, where the young princes were smothered and where Raleigh was confined. Adjoining is the Wakefield Tower, with walls thirteen feet thick. Passing through the Bloody Tower gateway to the interior enclosure, a large number of curious guns are seen, and the Horse Armory at the base of the White Tower is filled with specimens of ancient armor artistically arranged. In this collection the systems of armor can be traced from the time of Edward I. to that of James II., and there are suits that were worn by several famous kings and warriors. Above, in Queen Elizabeth's Armory, is more armor, and also trophies of Waterloo and other battles, and a collection of every kind of weapon in the Tower. There are also specimens of instruments of torture and many other curiosities on exhibition. [Illustration: THE CHURCH OF ST. PETER, ON TOWER GREEN.]
