Eleven swings have been installed outside Tate Modern's Blavatnik Building, as part of a large-scale interactive installation by Danish collective SUPERFLEX.
When One Two Three Swing! opened in October, Tate and SUPERFLEX promised that the installation would expand beyond the confines of the Turbine Hall into Bankside and potentially beyond.
On Monday Tate removed the barriers around the eleven sets of swings above the old oil tanks of Bankside Power Station on the south side of the gallery.
One Two Three Swing! continues until 2 April 2018.
