The Tower of London is one of the main London's places of interest. It is located on the north bank of the River Thames and is one of the oldest buildings.
At different times the Tower was used as a royal residence, fortress, prison, mint and, even, zoo. Today the Tower of London is the place where the Crown Jewels are kept.
Every day its doors are open for tourists. A few black ravens live on its territory. The walls of the Tower are still guarded by palace guards in historical outfits.
