This tower was originally built as part of Henry III’s curtain wall around the fortress and was constructed in c1239-41. During the end of the Elizabeth reign, it was used to house prisoners.  It is possible that it was called the Constable Tower because, at some point, the Constable’s lodgings were located in one of the buildings which used to adjoin it.

As part of the Fortress experience, the Constable Tower now contains a model that reconstructs the Tower of London in the middle of the Peasants’ Revolt, 1381. From the scene of the break-in to the execution of the Archbishop of Canterbury, Simon Sudbury, the Constable Tower tells the story of the only time the royal fortress was ever breached.
