of the basement have a modern plain brick barrel vault. The well, a plain ashlar pipe six feet in diameter, is in the south-western angle of the floor in the western chamber. The south-eastern chamber retains its original stone barrel vault. This forms the sub-crypt of the crypt below St. John's Chapel, and is lighted, or at least its darkness is made dimly visible, by a single small loop in the east wall. It is now known as "Little Ease," and is said to have served as the prison of Guy Fawkes. The basement chambers have boldly sloped recesses in the walls, with small loops high up in their heads, which afford the minimum of air and light; but as they were only used for stores, this was not of great importance. Ascending by the main staircase to the second floor, the same subdivision into three chambers is continued, but these were lighted by larger loops, that have been converted into larger windows at the time of Sir Christopher Wren's renovations in 1663. The crypt of the chapel opens from the eastern chamber, and has in its north wall a singular dark cell eight feet wide and ten feet long, in the thickness of the wall, in which Sir Walter Raleigh is said to have once been imprisoned. The western chamber has in its north-west angle a latrine, or garderobe, in the thickness of the wall. At the west end of its south face is a large original opening, with parallel sides, having niches in them. The masonry shows traces of where the arch and door jambs have been torn away and the present large window substituted, probably during Wren's alterations. There is little room to doubt that _this_ was the _original door of entrance_, placed, as is usual, some distance above ground, and probably reached by an external flight of steps, now removed, protected by a similar fore building to that of Rochester keep.[13] Proceeding by the main stair to the third floor, we enter first what is known as the "Banqueting Hall," which is lighted by four large windows, and has a fireplace in its east wall, with two latrine chambers in its north and east walls. Passing through a low doorway in the partition wall, we enter the great western chamber, which has a fireplace in its west wall, a latrine in its north wall, and is lighted by eight large windows. Two newel staircases in the western angles ascend to the battlements. In the south wall is a doorway leading to a passage at the head of a small newel stair, which, rising from a door in the wall on the floor below, formerly afforded a direct communication from the palace to the chapel of St. John upon the third floor, without entering the keep. At the foot of this stair, in the time of Charles II., some bones in a chest were discovered by workmen engaged in repairs, which were said to be those of the murdered Edward V. and his brother the Duke of York. These were transferred; by the King's instructions, to the vaults of Westminster Abbey.
