Tower Bridge 120th Anniversary

As well as looking rather spectacular from the outside, Tower Bridge offers visitors an incredible view of the Thames and some of London's finest landmarks from its high-level walkway, which is holding an exhibition charting the bridge's 120-year history. Tickets are normally £9, but admission to the Tower Bridge Exhibition will cost just £1.20 on its birthday, June 30. The offer is available to all visitors who pay at the ticket office on the day.
