this Sacramental plate is historically interesting, for these cups and plates have been used at the solemn hour when the Blessed Sacrament was administered to more than one illustrious prisoner on the eve of his execution. There is good reason for believing that Monmouth and William, Lord Russell used these sacred vessels shortly before mounting the scaffold. [Illustration: _Tomb of the Blount Family in Sᵗ. Peter’s Chapel._] At the back of the chapel of St Peter, and at the north-western angle of the Inner Ward, stands the Devereux Tower, which contains two storeys, the lower one being of massive masonry. This tower dates from the reign of Richard the First. In the Elizabethan survey of the fortress it is named Robyn the Devylls Tower, and in later times it was known as the Develin Tower, and as such it appears in Haiward’s plan. No record has come down as to the meaning of these names, but the present appellation dates from the reign of Elizabeth, when Robert Devereux, Earl of Essex, was a prisoner there. The upper part of the tower is modern, and modern windows have taken the place of the old loopholes in the 11 feet thick walls, a change which has destroyed the character of the building; formerly it was most gloomy and forbidding. A small winding staircase within the tower leads to a couple of prisons constructed in the thickness of the Ballium wall. A secret passage is supposed to have led thence, to the Flint Tower which stands to the east of the Devereux Tower, communicating also with the vaults under St Peter’s Chapel. Nothing remains, however, in the present modernised state of these passages and prisons to indicate their former appearance. Early in the nineteenth century the lower floor of the Devereux Tower was used as a kitchen and other offices connected with the ordnance; the upper portion was occupied by the Master Furbisher of the Small Arms. The old kitchen, beneath which is a dungeon, has a fine vaulted ceiling.
