First opening in 1863, the London Underground is quite a remarkable system, now having over 260 stations and 402km of track. Although I found it a bit disconcerting being so deep underground, I was also quite taken by the mazes of tunnels and stairs, many decorated in unique tile patterns. Originally, tile was used to help reflect the light from the gas burning lamps, and in some stations, the original tile work is mimicked. In other stations, and of course the newer ones, modern conveniences of escalators and elevators have replaced the winding staircases, the walls instead decorated with Hollywood movie and Theatre posters. I was more partial to the older style stations... the novelty of it all.
