Arthur Wellesley, Duke of Wellington
Appointed Constable of the Tower in 1826.
Wellington exerted a major influence: draining the moat, reorganizing the establishment of the Yeomen Warders and overseeing the building of the Waterloo Barracks.
Wellington had definite opinions about the role of the Tower and opposed its development into a museum, preferring the Royal Repository at Woolwich for the prizes from Paris in 1815.
However he insisted that all the guns captured in the Peninsular War and at
Waterloo should be preserved.
The Tower still mounts a battery of Waterloo guns outside the Waterloo Barracks, north of the White Tower.
