Monument record MRM 143 - Grace Cottage, Portal Avenue, Martlesham

A trial trench evaluation was carried out at the above site in advance of the construction of a rear extension to the house. One evaluation trench was excavated adjacent to the area of the proposed extension. The site is close to a well-preserved prehistoric bowl barrow (Scheduled Ancient Monument no. 21259; Historic Environment Record no. MRM 018). The evaluation revealed natural sand at a depth of approximately 0.65m below ground level. This is sealed by successive layers of subsoil, topsoil and turf. No archaeological features or deposits were identified and no artefacts were found (S1).
