The Tower of London is an ancient building complex at the edge of the city of London on the north bank of the Thames River. It stands on a small rise known as Tower Hill.
Crown jewels are valuables that belong to a king or queen.
Long ago one building was a fortress, another was a home for royalty and another was a prison until the 19th century. The outer walls of the Tower of London were once surrounded by a foully polluted moat, which was drained under the direction of the Duke of Wellington in the 19th century. London's notable ravens are kept inside the Tower grounds with clipped wings. Legend tells that when the ravens disappear it will mark the erosion of the Kingdom. The Tower of London has been residence to every Monarch from William the Conqueror in the 11th century to Henry the VIII in the 16th century.
