Yeoman Warders
The main entrance of the Tower of London is at the Byward Tower, where you'll find the so-called Beefeaters or Yeoman Warders.
Dressed in historic clothes, they not only guard the tower, but also give guided tours of the fortress. One of the about 40 Yeoman Warders is known as the Ravenmaster, responsible for the ravens that have been living here for centuries
Legend has it that the Tower and the kingdom will fall if the ravens leave. Hence King Charles II placed the birds under royal protection and the wings of the ravens are clipped to prevent them from flying away.
