A Roman temple at High Wood, Harpsden, near Henley, Oxfordshire

Over seven seasons of excavation, 2015-2021, South Oxfordshire Archaeological Group (SOAG) investigated the partial remains of a Romano-Celtic temple complex with the inner temple chamber or cella surrounded by a walkway referred to as an ambulatory. These remains are set within a rectangular temenos enclosure that encompasses a range of rooms to the north. These buildings appear to have suffered a catastrophic collapse in antiquity.

The complex overlies evidence of Late Iron Age/Early Romano-British exploitation of the site and there is evidence of a possible Beaker period burial in the locality.
