The medieval features on Thanet Earth dated to between the mid-eleventh century to the early part of the fourteenth (possibly extending to AD 1350). The activity is primarily agricultural in nature with significant elements of domestic occupation. A site wide system of enclosures appears to be intimately related to various trackways across the site. The activity around these enclosures has been grouped into a number of Medieval ‘sites’. Site 17 comprised the southernmost complex of enclosures (57, 58 and 67) adjacent to Trackway 30, was only partially exposed, about 170m south-west of site 16. The features at this site were difficult to interpret and date, though several phases of development were seen, all likely dating to the middle or later period of Medieval activity at Thanet Earth, c. between 1150-1350. A number of features, including structures were located within the enclosed area while a few other features were situated just outside or recorded as being cut by, or cutting, the ditch of the later enclosure.
