Britain’s tallest sculpture has been errected. It’s in Manchester and rises 180 feet. It’s a starburst of spikes “designed by Thomas Heatherwick and took 20 months to put together from 180 tapered steel spikes, connected 22 metres above the ground. To keep it anchored it has foundations weighing 750 tonnes, including a 400-square-metre reinforced concrete slab. The sculpture itself weighs 300 tonnes and leans at an angle of 30 degrees – 10 times more than the leaning tower of Pisa.”
