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.

It's got to be one of London's best-loved events: from the arrival of the eagerly awaited annual catalogue and the feverish planning of visits, to that autumn weekend when the city flings open its doors to citizens and visitors. Yup, it's Open House - time for Londoners to get up close and personal with buildings they normally can't access.
