Tower Bridge is one of the most recognisable landmarks in London together with Big Ben. The bridge was built in 1894 to a design matching that of the Tower of London.
The bridge is often confused with the London Bridge, which is the next bridge upstream but looks nothing like Tower Bridge.
Tower Bridge is open for traffic, and one can cross it by walking, cycling or with a car. The best views of the bridge are available when taking a river cruise or Thames Clipper under the bridge. Also, the opposite side of Thames from the Tower of London is a popular picture-taking spot.
There is tour available allowing for crossing the bridge on the top level that has a glass floor, and the route also takes you to see the machinery of the bridge.
The closest tube station is Tower Hill (District, Circle), around 5 minutes walking distance from the bridge. Thames Clipper has a pier next to the Tower of London.
