Summary

Lying directly to the S of Whalley Golf Club, a multivallate hillfort sited on a south-westerly-facing promontory at 122m OD. The enclosure has a maximum extent of 165m NW-SE by 110m transversely, enclosing 1.3ha. Protected by steep slopes in the W and elsewhere an inner bank with an external 6m wide berm, beyond which are three further banks and two medial ditches. The ramparts are badly mutilated except in the NW corner where the inner bank stands 1.5m high and the innermost ditch 6m wide, with the second bank 4m wide. Excavation for a water pipeline in 1957 (Tyson and Bu'Lock 1957) showed the inner bank to be constructed with a clay core revetted front and back with stone. The remaining banks are of earthen construction. The excavation also recorded an earlier rampart approximately 4m thick revetted at the front with large stones set on edge. This was later levelled and succeeded by the multivallate ramparts 6m further N at the break of slope. An entrance lies in the W which was shown to have a cobbled pavement. Pottery dated to 2nd century AD was discovered in an overlying deposit. Internally the surface appears to have been artificially levelled and excavations in 1970-1 prior to the destruction of the interior for a water trench discovered a number of stone packed postholes. Earlier in 1966 workmen laying a pipeline across the enclosure recovered a Bronze Age hoard which included gold and bronze artefacts. Subsequent excavations have unearthed further objects dating from the Neolithic to medieval periods indicating a long period of activity or occupation. The site is shown on 1885-1900 OS mapping. Probably Iron Age based on morphology.

Dating Evidence

Excavations in the 1960s and 1970s recovered medieval and Roman pottery and flint and chert objects dated to the Bronze Age and Neolithic periods. A Bronze Age gold bracelet and `tress or lock' ring and bronze objects including socketed axe heads were discovered by workmen in 1966. No finds of an Iron Age date are recorded and the site is dated to the Iron Age on morphology only.

Steep slopes in the W and elsewhere an inner bank with an external 6m wide berm, beyond which are three further banks and two medial ditches. In the NW corner the inner bank stands 1.5m high and the innermost ditch 6m wide with the second bank 4m wide. Excavation showed the inner bank to be constructed with a clay core revetted front and back with stone. The remaining banks are of earthen construction. An earlier rampart approximately 4m thick revetted at the front with large stones set on edge, was levelled prior to the construction of the multivallate defences.
