| Summary : A gatehouse of the Tower of London originating between 1275 and 1281. It was principally altered between 1717-1719 when the upper floors were rebuilt and the structure was re-faced in Portland stone. It bears the arms of the George I. The entrance passage was originally defended by two portcullises, the grooves of which are still visible inside the archway. The interior contains rare 13th century brickwork and a causeway on its eastern side, which originally contained a third drawbridge, links it to the Byward Tower. The tower is now used as a residence of one of Yeoman Warders. |
