Big Ben

The Clock Tower is the name of the famous tower of Parliament - more popularly known as Big Ben. UK residents can arrange a tour through their local MP. However, please be advised that space is extremely limited and early booking, 3-6 months in advanced, is strongly recommended. Overseas visitors cannot currently visit the tower. Big Ben is one of London's best-known landmarks, and looks most spectacular at night when the clock faces are illuminated. You even know when parliament is in session, because a light shines above the clock face.
