A Fact: The Tower of London served as a prison
It is undeniable that the Tower of London sheltered prisons. In fact most of the towers shelter cells in their basements, and they were not decorative: they really kept away from personalities. But in reality, not so much. The prisoners of the Tower of London were essentially important personalities, queens and kings, opponents, etc. There were also members of the clergy or aristocrats who had chosen the wrong camps during the war between the two roses, but also officers, Scottish rebels and even a king of France! The very first prisoner was imprisoned in 1100, shortly after the completion of the construction of the white tower. But it was not a great success. With the help of external complicities, he was able to make himself beautiful by using a rope hidden in a barrel.
