The Shard, one of London’s more obscure towers, is an engineering feat due to its construction and design. The tower, completed in 2012, stands at 1,016 feet tall, making it the tallest building in the United Kingdom and European Union. But the buiding is more impressive than just pure height, it encompasses 1.2 million square feet of floor area across 72 usable floors and is supported by 44 elevators (or shall we say lift?). The Science Channel manages to pack some interesting details and the construction of the tower into an Impossible Engineering short in under three minutes.
