Photograph of the entrance archway to the Bloody Tower at the Tower of London. The focal point of the image is a shadowy archway that covers a narrow cobbled street and leads to a brightly lit opening, framed by the spikes of a retracted portcullis. Beyond this can be seen Traitors' Gate, the water gate entrance to the Tower of London positioned below street level. 

The Bloody Tower consists of an upper and lower chamber. It derives its name from the 1560s when the two princes are believed to have been murdered by their uncle Richard III in the upper chamber. Important prisoners were also detained here, including two Archbishops of Canterbury, a Lord Chancellor and Sir Walter Raleigh.
