Tower of London

Her Majesty's Royal Palace and Fortress, more commonly known as the Tower of London (and historically as The Tower), is a historic monument in central London. the Tower of London stands the Norman White tower built in 1078 by William the Conqueror (reigned 1066-87).

It has also served as a place of execution and torture, an armury, a treasury, a zoo, the Royal, a public records office, an a observatory... Charles II was told that if the ravens left the tower, the empire would fail. Their wings are clipped, so they can't fly away. The Tower of London is reputedly the most haunted building in England. The ghost of Queen, Anne Boleyn beheaded in 1536 for treason against King Henry VIII.

In my opinion I think that this monument is one of the most impressives of London, because this build have a lot of history and is an incredible monument. This history starts in 1078 and since actually days this build is in a perfect conditions.
