Its most famous landmarks are Haden Hill Park and the historic Haden Hill House, both of which were constructed during the 19th century. The River Stour flows through Haden Hill, and formed the historic county boundary of Staffordshire (Cradley Heath) and Shropshire (Halesowen). The Halesowen side of the river later became part of Worcestershire, and in 1966 all of Haden Hill was moved into Worcestershire when the Staffordshire side of the river (originally in Rowley Regis Borough) became part of Warley County Borough.
