Five excavations in eastern Berkshire are described in this report. At Horton, investigation of penannular cropmarks revealed a complex Neolithic monument with clearly structured deposition of numerous artefacts, overlain by a series of late Iron Age and Roman features. Work on a pipeline at Barkham Square turned up a late Bronze Age burnt mound, a rarity for southern England.Very ephemeral traces at Fairclough Farm, Bracknell turned out to be remains of a middle Iron Age settlement.At Bath Road, Slough, late Iron Age and Roman field systems and other features were very reminiscent of the finds of these periods from Horton. Finally, multi-period occupation at Waylands Nursey, Wraysbury, ranged from the late Bronze Age through the Roman period and into the early Saxon. All of these sites, despite their differences, attest in their own way to the intensive exploitation of this small part of the Thames Valley, over a long period.
