Tower Bridge

Tower Bridge is a bridge in London. It crosses the River Thames near the Tower of London. The north side of the bridge is Tower Hill, and the south side of the bridge comes down into Bermondsey, SE1, an area in Southwark. It is far more visible than London Bridge, which people often mistake it for. If large boats need to sail under Tower Bridge, the two halves of the bridge lift up to let it under. Many tourists go to London see the Tower Bridge. (http://simple.wikipedia.org/wiki/Tower_Bridge)
