Also known as the Square Mile, the City of London is actually a small area east of central London. This is London's financial and business center where you'll find suit-wearing bankers and stockbrokers dashing around. The area is quiet at the weekend when the workers aren't there. It's well worth a visit as it's packed full of historical buildings right next to modern skyscrapers. And, there are loads of things to do for free.
The Ceremony of the Keys at The Tower of London is a 700-year-old tradition that takes place every night. Essentially it's locking all the doors to the Tower of London and the public is allowed to escort the warden, as long as they apply in advance.
As the Tower must be locked (it houses the Crown Jewels!) they never miss a night because you can't leave the door open, can you?
The Museum of London's mission is to inspire a passion for London. It documents the history of London from Roman times up to today. The museum features original artifacts from archeological digs and it hosts temporary exhibitions throughout the year.

The Gallery was established in 1885 to house and display paintings and sculpture belonging to the Corporation of London.
