Remains of multivallate, contour hillfort located on Tatchbury Mount, a prominent clay hill on NE edge of New Forest. River Test to E and its estuary to SE, Cadnam River and River Blackwater confluence to N. Moderate surrounding slopes. Now adapted as part of an ornamental garden for late 18th century house built inside the ramparts, extensively landscaped in 18th and 19th centuries, and now within grounds of Tatchbury Mount Hospital. Oval earthwork, NNE to SSW, encloses c. 1.8ha-2ha. Two banks between 3.5 - 4m high separated by terrace c. 6.0m wide, except along the W side, where smaller, and originally continuous bank between main banks. Terrace possibly site of infilled ditch. Two trenches excavated in advance of proposed development (Ingram 2005) recorded ditches/gullies. Access to house from N possibly follows line of original entrance. Chance find of Iron Age comb. On 1st Ed. OS map (1869). Undated.
