The river Irwell was once the hardest working and filthiest river in the world. Now it is an invaluable wildlife corridor within reach of thousands of people. This exhibition will explore the Irwell and its valley, from its source in Rossendale to its final destination at Salford Quays and the Manchester Ship Canal. Paintings, drawings, photographs and film will reveal its post-industrial landscapes and the wildlife which thrives there, often discreet and hidden from view. Free. Wed - Sun: 10am - 4pm,  late night Thursday until 8pm.
