The Tower of London has a history of a royal palace, an armoury and a powerful fortress but it is probably best remembered for being a notorious prison, a place of torture and death. Today, visitors can join a Beefeater on tour and discover the priceless Crown Jewels as well as hear numerous tales and learn the legend of the Tower's ravens. In addition to leading tours, it is the Beefeaters' duty to ensure the jewels remain safe.
