The BP Research Centre, Sunbury-on-Thames

Evaluation by P Moore and M Bagwell of PCA, for BP International Limited, and a subsequent watching brief, revealed that much of the site had been truncated by previous building work. Two trenches did reveal intact upper soil horizons, but no archaeological features; the discovery of a residual flint flake, probably of Mesolithic or early Neolithic date, was the only indication of activity of any antiquity.
