This contains several inscriptions carved by prisoners who took part in Wyatt's rebellion in 1554. Here are shown the block used at the execution of Simon, Lord Lovat, in 1747, the execution axe, dating from about the year 1660, some instruments of punishment, used for confining prisoners, and a model of the rack as it existed in the Tower in 1809.
Between the years 1831 and 1883 the Crypt was known as "Queen Elizabeth's Armoury" and contained many of the weapons now shown in the Weapon Room.
From the Crypt the visitor passes to the west into THE SMALL ARMS ROOM.
