(NS 2073 5932) Green Hill (NAT) Motte (NR)
OS 25" map (1972)
Though Green Hill was earlier thought to be a Viking burial mound, it is now recognised as a motte (V G Childe and A Graham 1943). It is about 16ft high, and is separated from rising ground to the N by a ditch. Its summit has been much interfered with and bears three modern masonry columns (called 'The Three Sisters' on OS 25" plan) said to have been erected by the astronomer Brisbane for mathematical purposes (J Smith 1895); it seems to have once been level and may have measured about 35ft by 20ft.
F H Groome 1901
Green Hill is a steep-sided, sub-oval mound, measuring about 12.0m by 7.0m across its flat top, upon which stand three masonry columns, each 1.0m square. On the NW is a depression, 5.0m wide and 1.0m deep, which may represent the end of a ditch. This is obliterated to the N by gardens. Where turf has been removed from the sides of the mound, a construction of earth and small stones is exposed.

This tree-planted and scrub-covered mound, about 6m high on its S side, is generally as described. Hemmed in by development, no overall view of its form is possible and its N side is now completely fenced off and hidden by scrub. Minor erosions show gravel bands on its W and S sides and the general contours of the area suggest it is likely to be entirely natural. There is no visible evidence to support this as a motte. A plaque states that the observatory pillars were erected in 1808.
