The works, involving the excavation of eight trial trenches, were carried out in June 2019 in order to evaluate the site of a proposed new racing stable complex Only two trenches contained any archaeological features or artefacts: in Trench 1, adjacent to the modern road, a drain and a trench were found associated with a row of five 20th century buildings seen on a map of 1960 and probably linked to the use of Upper Lambourn in WWII by the US military; and Trench 2 in the northern corner of the site, where a single small pit of Middle Bronze Age date was excavated, together with three associated stake-holes.
