Traitors' Gate, Medieval watergate in England
Traitors' Gate is a medieval watergate originally built for King Edward I, to provide a new water entrance to the Tower of London.
The gate was designed by the Medieval architect Master James of St George on the orders of Edward I between 1275 and 1279 to provide a new water-gate by which King Edward could arrive at the Tower.
Its name, Traitors' Gate, derives from the prisoners brought through it to the Tower, which often included traitors to the Crown.
Today, the gate is closed off to visitors but can be viewed from outside.
It's one of the most iconic symbols of British history, often depicted in art and literature.
