Located in fields adjacent the River Thame E of Quarrendon House Farm and centred at SP 79923 15629, a system of interconnected parallel and perpendicular ditches up to 2.5 metres wide extends about 272 metres N-S from the SW corner Quarrendon Water Garden earthworks to the River Thame, where the ditch links to the river as a tail drain. On aerial photographs taken in 2023 and recent remote sensing data, the ditches remain intact (1- 3).
