This is the Brian Catling Sculpture that was erected in September 2006 to mark the approximate area on Tower Green where 10 executions took place. It replaced a small plaque that was already on this site. Executions were rare inside the Tower of London and normally carried out on Tower Hill nearby. Those killed here would have been because it was too much of a risk of a riot for them to be killed publically on Tower Hill. The Tower of London signposts this area as the scaffold site. All who were executed are named on the memorial including 3 Queens. The best known of these would be Queen, Anne Boleyn, accused of adultery and beheaded by a French swordsman on May 19 1536. In 1861 Queen Victoria requested a plaque be placed on the spot where Anne Boleyn was killed which is where this memorial is placed.
