The site was a major trading centre, associated with, and under the control of, a middle Anglo-Saxon estate centre focussed on Sleaford. This site is important since it was in use before the late seventh century with a significant concentration of high value continental coins (Merovingian tremisses) and with strong trading links with the continent. {1} An area of intense middle Anglo-Saxon activity identified primarily through metal-detecting, and comprising one of the county's largest assemblages of middle Anglo-Saxon finds. The finds include some 89 coins and 23 artefacts of the types commonly found on so-called 'productive' sites such as brooches, hooked tags, tweezers and strap-ends. The site is situated on a spur of high ground projecting out from the Fen Edge. This spur represents the closest piece of high ground between Kesteven in the west and Boston Haven in the south-east. The site is generally interpreted as a high-status middle Anglo-Saxon trading site which emerged from earlier activity extending back into the early Anglo-Saxon and perhaps Roman periods. It has been suggested, given the high status of the site and the high value coinage recovered here, that the site was an entrepot exporting slaves and high value merchandise to the continent. Activity appears to have continued into the ninth century and beyond, the nature of this activity appears to have changed from one which saw high-level engagement with international trade, to one which perhaps took on a more regional or local focus, or even a period of decline or abandonment. The numismatic evidence on its own indicates activity between the seventh and mid eighth centuries, with a peak in coin-loss in the first half of the seventh century. However, the dates of the artefacts suggests some continued activity beyond AD 750 perhaps continuing into the eleventh century at a low level. {2} A numismatic analysis of coins from the site has catalogued 269 coins. The coins date from the mid sixth century to the mid eighth century. The analysis identified two successive monetary phases on the site. The first from the second half of the sixth century continuing to the third quarter of the seventh century comprised high value coinage from Merovingian Gaul indicating an important trading settlement with links to the continent. The second phase, from about AD 715 to about AD 750, comprising mostly foreign coinage from the Low Countries, Dorestad especially, indicating a further period of intensive trading activity with the continent. {3}
