Report on programme of trial trenching undertaken on land at Torksey Lock, prior to development of the site. Sixteen trenches were excavated, each measuring 20m x 2m. A series of ditches, gullies and pits which relate to the features recorded during an earlier magnetometry survey were identified. The features contained Roman pottery from the 2nd-4th centuries, though some residual Iron Age pottery was also recovered. An area of late Roman domestic activity was also identified as a large assemblage of pottery was recovered from a layer sealing the earlier enclosure. Finds on the site also included animal bone fragments and cereal grains. The features are likely to be of agricultural origin, and indicate a nearby domestic settlement. The abundant Roman pottery is likely to be associated with the Roman kilns to the north of the site which were excavated in the 1930s.
