(grid reference SJ53387341) It is listed as a Scheduled Ancient Monument.
[1][2][3] The motte is a cone shaped mound, 2.8 metres (9.2 ft) high; it has a diameter of 23 metres (75 ft) at the base and tapers to 6 metres (20 ft) at the top.
[1] Historians used to think that the motte was a large barrow.
The stone steps and concrete foundations of a summerhouse not contemporary with the castle are excluded from the protection of the scheduling.
There have been limited excavations on the site by antiquarians.
