At 215 miles long and neatly dividing London between North and South, the River Thames is the silvery thread that provides continuity for a City that is always changing. The sinuous loops and eccentrically named reaches provide the focus for some of London's greatest sights.

A viewing gallery has opened on top of the new skyscraper at 22 Bishopsgate.  Visitors to London can get views of the City without paying if they find the London Eye or The Shard too expensive. It joins the Sky Garden on top of the Walkie-Talkie building as a viewing platform which is accessible to the general public and free of charge. Café/bars serving hot and cold drinks can be found in both locations, but visitors are under no obligation to buy anything. Both viewing platforms have free toilet facilities.
