Ancient Origins and Archaeological Significance

Oldbury Castle hillfort stands at approximately 250 meters above sea level on the ridge of Cherhill Down, west of Avebury. Originally constructed during the Bronze Age as a hilltop enclosure with a bank and ditch, it was later expanded in the Iron Age into a bivallate hillfort featuring two substantial banks and ditches. Archaeological surveys have revealed a complex defensive system, including an inturned entrance on the eastern side and a cross-rampart dividing the interior. Pottery fragments dated to the 2nd and 3rd centuries BC, alongside Bronze Age burial urns and flint daggers, testify to its long history of human activity and ritual significance.

Landscape and Defensive Features

The fort’s earthworks crown the skyline of Cherhill Down, with the western side showcasing impressive multivallate ramparts that blend naturally with the steep escarpments. The northern side is protected by a steep scarp slope, providing natural defense. The site’s topography varies between 235 and 258 meters, with the highest points offering commanding views across the surrounding Wiltshire countryside. The hillfort’s layout and defensive features suggest it was a strategically important stronghold, controlling access along ancient routes and overlooking the fertile downlands.

The hillfort and its environs form part of a wider archaeological and natural heritage area, with nearby Bronze Age barrows, cross dykes, and ancient trackways enriching the visitor experience.
