The ArcelorMittal Tower is finally complete! To celebrate, here’s a gorgeous timelapse video of the Tower being built in the Olympic Park over the last couple of years.

At 114m, it’s officially the tallest sculpture in the UK. There’s a central lift which will take you up to see the spectacular views from the top; a spiral staircase winds down the central core to bring you back down to earth again.

The Tower officially opens to the public on 28 July.

I’ve just got back from an announcement at City Hall about an exciting new tower, called ArcelorMittal Orbit, commissioned for London’s Olympic Park.

Mayor of London Boris Johnson described the tower, which at a height of 118m will be Britain’s biggest piece of public art, as a “beauty”.

Although it’s currently called the Orbit, Boris also suggested London’s new red steel tower might be called a “giant treble clef, a mutant trombone, or a hubble bubble” – the latter in reference to its likeness to a shisha pipe, which wasn’t something I’d thought of…

Whatever Londoners decide to christen it (and I’m sure we will!), it’s certainly an exciting new structure. Anish Kapoor talked at length about his inspiration for the tower, acknowledging Gustave Eiffel’s 324m Paris landmark, as well as explaining how he hopes Londoners and visitors will make the journey around, and up and down the tower, with real a real sense of participation.

The £19.1m design incorporates the five Olympic rings, and has panoramic views of London from the top. As well as a walkway up the tower, there’ll be high-speed lifts taking 700 people per hour to the top. There’ll be a viewing platform up there, as well as a restaurant.

And when’s it going to ready? Well, the construction starts to “build itself” in clever sections in the next couple of months (with no scaffolding, Anish explained), and the tower will be ready for visitors in November 2011. The restaurant will come a bit later.

The Orbit will be on site for years to come, providing London with an exciting new visitor attraction in Stratford.

What do you think it should be called? The Stratford Scribble? Or The Scoubiedou? Let us know in the comments below!
