Check out the Parliament building and the newly restored Grande Bretagne Hotel. Also, catch the changing of the guards in front of the Parliament every hour on the hour. Their uniforms and walking style are very fun to see. Make sure you don’t stand on the wrong side of them if you want to take a picture. If you accidentally do so, they will knock their gun and, as they are not allowed to speak, someone else from the guard will kindly ask you to change position.
