Let's start our visit at the Bloody Tower by hearing a little bit about it from one of the Yeoman Warders, also known as "Beefeaters." These men (and one woman) are all retired from the British Royal Army, serving at least 22 years. Their duties at the Tower include safeguarding the crown jewels, participating in the Ceremony of the Keys every night, and acting as tour guides. They also live in the Tower of London.
Here is a painting of Edward V and Richard, Duke of York:

The two boys, often called the Princes in the Tower, lived in the Tower (remember that it was also a home for royals) during the summer of 1483. Edward V's mother allowed it because she thought it was so that her son could prepare for his coronation (a ceremony crowing the king or queen.)
Sadly, the boys disappeared. No one's completely sure about what happened to them, but a popular theory is that they were killed under the instructions of their uncle, Richard III, who wanted them out of the way so that he could become king.
In 1674, two skeletons of boys were found near the White Tower and were presumed to belong to the two princes. Forensic tests in 1933 were not able to prove (or disprove) their identities. The remains were placed in Westminister Abbey.
