Certain Ordnance Survey maps before the Second World War, closer to Sipson Green and the adjoining Harlington Corner (localities of the Bath Road), show an earthwork, 300 metres due south of where New Road, Harlington meets the Bath Road, that had been excavated in 1723 by order of William Stukeley. He believed it to have been a Roman settlement, and named it "Caesar's Camp".Cotton, Mills & Clegg 1986, p. 12
