To the S of Boston Road, Sleaford a possible Iron Age rectangular palisaded enclosure. The site borders the line of Marham Lane, the main Roman Road from Bourne to Lincoln. It was discovered in 1991 during a trial excavation prior to development. Two sides of the enclosure, both 40m in length were exposed. Excavation showed intercutting close-set post holes each approximately 203mm in diameter which possibly formed part of a massive timber palisaded structure of a 'ritual or defensive nature'. A possible entrance has been identified in the E fronting on to the precursor to Mareham Lane. Four post holes, possibly representing a raised granary and pits containing ashy deposits were also excavated. An internal palisaded division was also recorded. Two ditches, one 49m in length, the other 31m with a 5m break, possibly an entrance, were recorded radiating out from the enclosure. Middle Iron Age pottery, animal bone and iron slag were recovered. Not recorded on OS mapping.
