Sally Williams has been up the Orbit tower and discovered how the whole idea began.
The giant sculpture towering over London's Olympic park will remain closed to the public for eighteen months after the games.
The ArcelorMittal Orbit was commissioned by London mayor Boris Johnson as a work of art and viewing platform.
It is expected to attract five thousand visitors a day when it opens on July 28th - the day after the opening ceremony of the 2012 Olympics.
But the 2,000-tonne structure will close at the end of the Parlaympics.
The post-games redevelopment of the Olympic Park means the Orbit will not re-open until Easter 2014.

Set next to the stadium it boasts views across the whole of london and beyond... And it's not a bad spot to watch the 100 metres from! Entry during the games will be by ticket only.
The centrepiece of the Olympic park, the 120 metre tall Orbital, designed by Anish Kapoor, will officially be opened today.
