 Gabo donated his bronze maquette to the Tate Gallery in 1969, and then donated two plastic models in 1977.The work was installed in 1975 in the centre of a circular pool of water in a square garden at St Thomas' Hospital, with the River Thames to the west and Westminster Bridge Road to the north, and new hospital buildings to the east and south.It is a working fountain, with water emitted in streams from some of the sculpture's curved edges.
