Renewed excavation at the Iron Age hillfort of Oldbury, near Sevenoaks, Kent, in 1983 and 1984 was designed to effect a comparison with earlier excavation in 1938 and to relate the hillfort itself to others on the Greensand of Surrey and Kent. Re-examination of the defences suggests construction in the first half of the first century B.C. and questions the supposed refortification against the Roman invasion of A.D. 43; activity at this time and later in the Roman period is thought to reflect quarrying for stone. Some evidence for internal activity was recovered, but the scale was too slight to indicate permanent occupation.
