Teessaurus Park is a 10 acre urban grassland recreational area and sculpture park opened in 1979 in the Riverside Park light industrial estate, Middlesbrough, on the southern bank of the river Tees. It was built on a former slag heap in what was the Ironmasters district and represents, without any irony, the iron and steel industry that used to exist on the site and in the area. The park has its own small car park and has become something of a nature reserve.
