A single trial-trench, measuring 10.0m x 1.8m, was excavated by Colchester Archaeological Trust in February 2020 at 5 Yorick Road, West Mersea, in advance of the construction of a detached bungalow (and following the demolition of the existing dwelling). The trench was excavated through a modern demolition layer (L1, 0.1-0.17m thick) and subsoil (L2, 0.13-0.18m) onto natural sands and gravels (L3), encountered at 0.27-0.3m below current ground level. A ditch containing a small quantity of Bronze Age pottery was excavated, as well as a Roman or post-Roman ditch, a modern pit and an undated ditch and gully.<1> A series of linear features extended through the trench on a N-S alignment. Ditch F1 measured 0.86m wide x 0.31m deep and contained pottery (18 sherds weighing 228g) dating to the Middle Bronze Age, as well as a small quantity of baked clay (9 sherds at 52g). There were rims from two urns (EVE: 0.09), one of which is decorated with fingernail/tip impressions along the top of the rim and a row of pre-firing perforations (c.0.5mm diameter) about 1cm below the top of the rim. F1 cut tree throw F2. A small fragment (4g) of medieval or post-medieval peg-tile found on the surface of this feature was either intrusive or had been disturbed during the excavation of the trench. No dating evidence was recovered from the other N-S aligned linear features, gully F5, which was 0.54m wide x 0.05m deep, or ditch F6, 1.06m wide x 0.48m deep. Ditch F4, which was of Roman or post-Roman date (it contained three sherds (143g) of abraded Roman tile), lay on an E-W alignment. The ditch extended beyond the limit of excavation but its exposed extent was 0.5m wide x 0.2m deep. Pit F3 was also uncovered. Debris including CBM, concrete and tarmac were observed on its surface, indicating that it was modern, and so it was not excavated.
