Skylon was designed to counter the materiality of the nearby Dome of Discovery.
It was a needle suspended in mid air by tension cables and floodlit at night.
Skylon was destroyed on the orders of Winston Churchill in 1952 for being a symbol of socialism. The cables were cut and it toppled over into the Thames. The remains of Skylon are believed to still be on the bed of the Thames where it feel.
There have been multiple plans to re-erect it, the most recent in 2004, but so far a lack of funding to pay for the estimated £800,000 budget has prevented this.
