The B of the Bang was a £1.42 million 56m-high sculpture of 180 giant spikes, erected outside the City of Manchester Stadium to celebrate the 2002 Commonwealth Games.
Safety problems happened soon after it was completed in 2004 when one spike came apart.
Eventually 22 more were removed as a safety measure.
The object was rewelded and fenced off.
It continued to cause concern and debate over its future.
Finally Manchester City Council took legal action against Heatherwick studio and their subcontractors, who in November 2008 agreed to pay £1.7 million in damages.
The installation was removed in 2009.

The 'East Beach Café' is a building on Littlehampton Sea Front, West Sussex, UK created by Heatherwick.
Commissioned in 2005, the large steel structure houses a Café by daytime and restaurant in the evening.
The concept allowed the steel to rust and the colours to develop over time before being fixed in a transparent oil.
It won the 2008 RIBA Award in the South East region.
