Mount Manisty is a large man-made hillock located between the Manchester Ship Canal and the River Mersey 1.5 miles (2.4 km) northwest of Ellesmere Port in Cheshire, England. The mound, which is 100 feet (30 m) tall, was created from earth excavated during the building of the ship canal between Eastham and Ellesmere Port in the late 19th century. The feature forms a narrow elevated stretch of land between the canal (this section of navigation is known as Manisty cutting) and the river.
