The above ground, underground station of Edgeware Road. Confused? Much of London's underground is actually at ground level. This station was built as part of the Metropolitan line in 1863. It now serves the Circle, Hamersmith and City, and District lines.
It was the site of the London 2005 bombings, killing six people.
In recent weeks the messy construction site has revealed a building covered in these pretty tiles, turning the station platform into a much nicer place to wait for your train.
