Tower of London

If you ever get the chance to visit London, don't linger for too long gazing at the bridge open the bascules, and do justice to the Tower of London instead. Ever since it was founded by William the Conqueror to assert the Norman power, the fortress has been the setting for some of the most momentous events in European and British History. It has protected, housed, imprisoned and seen many a life taken away. By the way, don't lay your head where Ann Boleyn did before she was executed and have a picture taken of you - it's gross!. What you can do is marvel at the glamorous Crown Jewels, learn the names of all ravens roaming about the complex, and listen to blood-curdling ghost stories born in reputedly the most haunted building in England.
