Places to visit in London (II): Tower of London

Just some metres from Tower Bridge, The Tower of London rises in the horizon defining the medieval character of the city. Most history of London is condensed in this place. It is the oldest building in the city and was always used as fortress, although it has also been a Royal Palace (with Charles II and Henry III), as a prison (for criminals, but also for kings and queens), as the treasury and even as the Royal Zoo for three hundred years. The Tower of London is divided in different areas (The White Tower, Tower Hill, The Traitor's Gate, The Salt Tower, etc.). It's a compulsory visit if you ever go to London. Don't miss it!
