Hartshead Pike is a stone tower on top of Hartshead Hill overlooking Ashton and Oldham. The existing building was constructed in 1863 but there has been a building on the site since at least the mid-18th century, although the original purpose is obscure. The pike might have been the site of a beacon in the late 16th century. It has a visitor centre and from the top of the hill it is possible to see the Jodrell Bank Observatory in Cheshire, the Welsh hills, and the Holme Moss transmitter in West Yorkshire.
