Evaluation by R Poulton of SCAU, for Hencan Ltd, on an area west of the main 17th century house revealed no features or finds of archaeological interest. Although the site was found to have been much disturbed, this was not sufficient to have removed all traces of the buildings and features associated with the medieval manor house known to have existed at Henley. This may indicate that the present Henley Park is not located on the former manor house site. A watching brief on works to the foundations of the south wall of the main house revealed re-used chalk mouldings from door and window frames, of probable medieval date; clearly there was a substantial medieval building in the vicinity.
