Bird's eye view from Tower Bridge
A new glass walkway which offers guests a bird's eye view of the River Thames below has been revealed at Tower Bridge in London.
Tourists can test their head for heights by walking across the glass strip, which is suspended 42 metres up in the air.
The walkway is 11 metres long and cost £1million to build.
It offers visitors a new look at the famous bridge beneath them, including when it raises to let boats through.
