Built by King Edward I in the 13th century as a water gate to provide access from the Tower of London to the River Thames, the name ‘Traitor’s Gate’ came to be applied to this portal in Tudor times in relation to those accused of treason who were brought into the tower under its arch.
The double gateway is part of St Thomas’s Tower, which was designed by a Master James of St George, and behind it is a pool which was used to feed water to a cistern on the roof of the White Tower. While the gate was originally built to give access directly to the river, Traitor’s Gate now sits behind a wharf which runs along the river bank (and where can be seen the bricked up entrance says ‘Entry to the Traitor’s Gate’ – this was bricked up in the 19th century when embankment works were carried out)
Sir Thomas More, Sir Walter Raleigh and even the future Queen Elizabeth I (when a princess) were among those who were brought in by barge through the Traitor’s Gate (their journey would have led them under London Bridge where the heads of executed prisoners were on display). Whether Henry VIII’s disgraced Queen Anne Boleyn entered the tower through the gate remains a matter of some dispute.
