At 72 storeys, The Shard, or London Bridge Tower as it is also known, is the UK's tallest building and the second highest in Europe. It is a vertical town made up of restaurants, offices, a health clinic and apartments.

Eight "shards" of transparent, reflective glass make up the exterior. They are dinted and angled to reflect the movement of the sky rather than the city below, enhancing light internally. It has become a key feature of the capital's skyline - its height and form mean it can be seen on foot, from trains and from aeroplanes as people enter London.

Architect William Matthews of the Renzo Piano Building Workshop, says the slim, pyramid shape of The Shard was inspired by a church spire. "It's a very elegant solution as to how to build a tall building against the sky," he says. "An elegant form and the idea of a spire came to us very early on."

Transparency was also an important feature of the design. The clarity of the glass allows the various uses of the building - and how they change throughout the day, with lights going on and off - to be visible. A defining element of the building is how it works with the light, shifting from reflecting a grey sky to the brightness of the sun.

A high-speed lift rises six metres per second, linking the offices and accommodation and taking the public to the viewing galleries on floors 68, 69 and 72. From there they are offered a 360-degree view for up to 40 miles.
