SDO14009 - 17 Sweethill Road, Southwell, Portland, Dorset. Archaeological Evaluation, May 2011

In May 2011, Terrain Archaeology carried out an archaeological evaluation in the grounds of number 17 Sweethill Road, Southwell, Portland, Dorset (centred on NGR SY68526997). Four evaluation trenches were mechanically excavated within the garden area, comprising a c. 0.5% sample of the land plot. These revealed undated colluvial deposits containing occasional waste flakes of Portland chert and trace amounts of probably late prehistoric pottery over paler Late Pleistocene head deposits. A shallow northwest–southeast aligned feature exposed in trenching at the southeastern end of the garden may be part of a ploughed-out lynchet boundary, probably originally of medieval date.
