The Shard in London

What is now the European Union’s tallest building, London’s 95-story Shard — with offices, a hotel, apartments and restaurants — opened its viewing deck to the public on Feb. 1.

The main viewing gallery, on the 69th floor, is 800 feet up, more than twice as high as any other London viewing point. The 360-degree view is up to 40 miles on a clear day. Digital telescopes with touch screens allow zooming in on points of interest, with text descriptions displayed.
