The castle is located north of the River Bollin and south of a deep ravine (grid reference SJ74798598).

[2] The lack of documentary evidence relating to the castle may be attributed to the short term nature of the timber construction; motte-and-baileys were quick to establish and would not necessarily have been used for long periods.

[2] A coin found on the site dating to the reign of Henry II, 1154 to 1189, may indicate that the castle was built during this period.

[1] Volunteers from South Trafford Archaeological Group (STAG) and students from the University of Manchester carried out a measured survey of the castle's earthworks in 1997.

[6] The remains of Watch Hill Castle consist of two parts: an artificial mound (a motte) and an enclosure (a bailey).
