The John Nash-designed Oxford Circus is at the very heart of central London. It is the location of the fourth busiest Tube stop, and the busiest without a National Rail stop sharing the same station. The German artist Hans Unger, who was a very popular Art Nouveau artist of his day, created tile murals for the Victoria line platforms in the Oxford Circus tube station. Oxford Circus serves Oxford Street and Regents Street, both major shopping thoroughfares. The upscale Bond Street is also nearby. Numerous retailers have their London flagship stores on these streets, including Topshop, whose store at Oxford Circus is the world's largest fashion store. BBC also has its Broadcasting House nearby.
In 2009, Oxford Circus got a new diagonal pedestrian crossing in addition to the more conventional horizontal and vertical ones; the new crossing is partially modelled after Tokyo's Shibuya crossing.
