Thorganby Giants Hill has been described as a probable Timber Castle.

There are earthwork remains.


Medieval promontory partial ringwork survives as earthworks. It lies on a natural spur between the floodplains of the River Derwent, lying to the east and a tributary named the 'Old Derwent' to the south. The earthworks form an arc on the north-west side of the promontory. The massive external ditch is 2m deep relative to the ground surface and the inner bank is 2m in height. Geophysical survey revealed the ditch extends further eastward from the earthworks. (PastScape)

The remains would appear to fall into the category of earthworks classified by King & Alcock as partial ringworks, rather than a motte and bailey. Situated on a natural SE spur between the flood plains of the River Derwent and the Old Derwent, which afford substantial protection on two sides, the work consists of a well-spread crescentic rampart with a massive external ditch on the NW side. This extends almost across the neck of land, except for a gap 25.0m wide, probably original, near the E flank. The ditch is 1.9m deep externally and 3.4m internally, while the rampart, much reduced by ploughing, now only attains a maximum height of 0.9m. The slightly greater inner ground level, approximately 0.6m above the outer, can be attributed to natural soil accretion. (PastScape ref. Field Investigators Comments–F1 DS 10-MAR-72)

A magnetometer survey was carried out over Giant Hill, Thorganby Grange, N. Yorkshire, for inclusion in the Humber Wetlands Project. The aim was to search for any buried archaeological features associated with the extant earthwork, believed to date no later than the 11th century AD. The data yielded disappointing results, dominated by a system of modern drains, and showed few archaeological anomalies. (Summary of Bray 1998)

Possible castle although may also be Viking camp (or both). There were several manors in Thorganby recorded in Domesday some of which can not be traced after the C14.

Minor archaeological investigations, such as watching brief reports, and some other 'grey' literature is most likely to be held by H.E.R.s but is often poorly referenced and is unlikely to be recorded here, or elsewhere, but some suggestions can be found here.
The possible site or monument is represented on maps as a point location. This is a guide only. It should be noted that OS grid references defines an area, not a point location. In practice this means the actual center of the site or monument may often, but not always, be to the North East of the point shown. Locations derived from OS grid references and from latitude longitiude may differ by a small distance.
