Yeomen Warders
Since 1784 the tradition has been for the Constable to be a senior military officer, usually a general officer. Perhaps the most famous Constable was Arthur Wellesley, 1st Duke of Wellington, who served from 1825 to 1852. During his tenure, the royal menagerie and record office were removed and many buildings were restored to their medieval state. The moat was drained and converted into a parade ground. Yeomen Warders were no longer permitted to buy and sell their places but were to be drawn only from sergeants in the Army. To His Grace's displeasure, tourism at the Tower increased during his Constableship.
