Joseph Ingleby’s steel sculpture – entitled Turtle Storm – is a familiar attraction near the lake. It was donated to the council – then Thamesdown – by the Dufty family in 1994 before finding its home in the park the following year. Joseph based the sculpture on the suffering of turtles because of nuclear testing in the Pacific Ocean during the 1980s. He said: “I wanted it to be made in an abstract way and the way I was expecting it was to be metamorphic, so showing things changing with the shell landscape seen above. “My ideas are the balance between the man-made and the natural environment so there is that imbalance there throughout my work.
