Summary

Discovered in 1967 within the grounds of the RSPB Bird Sanctuary at Sandy Lodge, a small hillfort of 0.8 ha lying on a promontory 236m to the SE of Galley Hill (Atlas No. 3298). The two sites are separated by a narrow dry valley and clearly visible from each other (Dyer 1971). Oval in plan it measures 75m E-W by 150m transversely and is naturally defined on all sides except in the N where a 10m wide and 3m deep ditch cuts across the neck of the spur. Limited excavation by Dyer in 1969 across the rampart showed that the ditch was created from an artificially deepened natural dry valley that cut across the neck of the spur in the N. It had an irregular, stepped appearance suggesting it was deepened as a series of pits that had not been joined together and therefore possibly unfinished. The angular rock-cut surface appeared unweathered, suggesting it was open only for a short time (ibid.). Sandy material from the ditch had been used to construct a glacis rampart 1.7m high but diminishing in the E where the natural depth of the dry valley required no additional clearing out. Thin lines of grey sand within the bank were interpreted as possible residue from former branches or wattle, with stacked turves used the stablise the rear of the bank near the entrance. The front of the bank had been faced with a low sandstone blocks approximately six courses deep, some of which had tumbled into the ditch. An entrance lies In the NW, 20m from the eastern side of the spur surviving as a rounded ditch terminal and a relatively unworn causeway 10.3m wide. A single post-hole 0.6m in diameter, possibly for a gate was found at the northern end. The western side of the entrance along with the bank and ditch were quarried for sand in the 19th century and the causeway might have once been wider. No structural features were discovered within the interior during the investigations in 1968 but a number of early Iron Age pottery sherds were recovered, together with Mesolithic flints. The incomplete nature of the features and small number of finds, and the lack of evidence for use of the causeway was seen as evidence for short-lived occupation (Dyer 1971, 14). The site is not recorded on OS mapping.
