The City - a historical centre of London and also called ‘The Square Mile” for its shape and size. A lot of the medieval buildings were destroyed during The Great Fire of London and World War II.
Simply by walking through the City streets you can see:
The Monument - climb to the top to get a unique view of the city and to see exactly where the Great Fire of London started back in 1666.
Old Bailey - the most well known criminal court in the world, can be accessed on weekdays in between 10AM-1PM and 2PM-5PM. Security is (unsurprisingly) very strict. Bags, food or phones are not allowed and storage facilities are not provided.
Tower Bridge - a bridge built in the 19th century. It still opens when needed to let ships go through. For £6 you can access the Tower Bridge museum and get to the top for amazing city views.
Tower of London - classified as the most famous fortress in the world. Through its 900 years of its existence it has been a royal palace, prison, place of execution, and now houses the Crown Jewels of the United Kingdom.
