No 5: Tower of London
The Tower of London has served many purposes in its time.
For nearly 900 years it served as an infamous prison, eventually becoming a treasury, the home of the Royal Mint, and a public records office, among many others.
The Tower is now home to the Crown Jewels of England and open to the general public to view the 23,578 gems.
Actors dressed as knights make you feel like you stepped into a different time period, truly making the tower come alive.
