Where: Tower Bridge, London SE1

What: Tower Bridge, with its pale blue lines and Gothic style, has stood over the River Thames in London since 1894 and is one of the worlds most recognisable bridges.

The bridge has an exhibition (the tower bridge experience), which describes how it was built, its history and the role it has played in the development of London. There are animatronics and interactive displays plus fantastic views of the Thames.

You can also enjoy breath-taking views from the high-level Walkways and visit the Victorian Engine Rooms, home to the original steam engines that used to power the Bridge.

The walkways at tower bridge have specially designed windows which allow visitors to take photos of the views without them being obscured by the glass.
