Here’s something that not many London locals know let alone tourists – There is a tour which lets you climb to the top of Big Ben!

The Clock Tower is the name of the famous tower of Parliament - more popularly known as Big Ben. Although often referred to as Big Ben, this is actually the nickname of the bell housed within the Clock Tower - and Big Ben's official name is the Great Bell.

What the tour covers

A tour will take you up the 334 spiral steps to the top of the 150 year old Clock Tower to hear Big Ben strike the hour. As well as seeing a spectacular view of London from 62 metres up the tower, you will also go behind the clock faces and have the opportunity to visit the mechanism room to learn about how the clock works in the 21st Century.
