ArcelorMittal Orbit - London 2012 Olympic Park, Stratford, London, UK - Look-Out Towers on Waymarking.com

The London 2012 website (visit link) tells us about the 'Orbit':

"Standing 115 metres high, the Orbit is the tallest art structure in Britain – offering stunning views over the Olympic Stadium, Olympic Park and the whole of London.

Located in Orbit Circus in the south of the Olympic Park, the Orbit is London’s major new visitor destination – both during the Games and beyond.

The design and construction
The search for a permanent artwork on the Olympic Park was instigated by the Mayor of London’s Office, which invited more than 30 international artists to submit their ideas for a sculpture of up to 180 metres tall.

Following a lengthy selection process, the Orbit – designed by internationally acclaimed artist Anish Kapoor – was chosen.  As well as promising a unique moment and experience for visitors, the spiralling red structure successfully represented both London and the UK, and was reflective of the five Olympic rings.

Construction of the Orbit started in November 2010, and was completed by April 2012.

The Orbit experience
The Orbit is more than a work of art – it’s an entire experience. After going through the small, intimate entrance to the Orbit, visitors make their way into an elevator with viewing portholes, which takes just 30 seconds to pass through the Orbit’s twisting form and reach the viewing platform 85 metres high.

Once it’s reached the platform, visitors can step outside the lift and experience the Olympic Park in a whole new light – as well as enjoying stunning views of London’s cityscape. It’s also possible to look straight down the centre of the Orbit to the ground below – though this isn’t recommended for the fainthearted!

To conclude the experience, visitors are encouraged to stroll down the spiral staircase that twists through the Orbit, enjoying even more amazing sights."
