The Lieutenant of the Tower of London serves directly under the Constable of the Tower. The office has been appointed at least since the 13th century. There were formerly many privileges, immunities and perquisites attached to the office. Like the Constable, the Lieutenant was usually appointed by letters patent, either for life or during the King's pleasure.[1]
The Lieutenants had custody of many eminent prisoners of state, including Anne Boleyn, Sir Thomas More, Lady Jane Grey, Princess Elizabeth (later Queen Elizabeth I) and Sir Walter Raleigh. At least five of the Lieutenants, Sir Edward Warner,[2] Sir Gervase Helwys,[3] Isaac Penington,[4] Colonel Robert Tichborne,[5] and Sir Edward Hales,[6] themselves later became prisoners in the Tower.
