An area of activity during the Romano-British period (AD 43-410) was noted to the north of the Kingsmead site, and represents a large-scale farmstead dating from soon after the conquest to well into the late Roman period. Although no structures were recorded of this date, a large and complex farmstead formed of large enclosure ditches, pits and waterholes was developed, possibly to produce goods to be traded at nearby Pontibus (Staines-on-Thames).

841 Decorated samian

Pottery recovered from the farmstead suggests an uninterrupted occupation throughout the period, and evidence has shown that the farm grew over time, as more and more enclosures were added. Such continuity suggests a period of prolonged and intensive period of agricultural activity.
842 Roman shoes
The general intensification and nature of the landscape during this period was noted in the artefactual evidence recovered from the site. Pottery included decorated samian ware, suggesting a certain status to the Romano-British population at Horton, whilst specific artefacts have suggested a wider network of trade and exchange. These include a hippo sandal (a type of horseshoe), farm tools, and a small number of personal items, including brooches, a finger-ring and a copper alloy spoon/scoop from a toilet set. A rare bronze cauldron may have been used as a votive deposit, whilst four leather shoes were found from separate features within the farmstead.
843 Roman farm implements
There is very little evidence for Saxon activity from the site, although a single burial was found. The scarcity of evidence may suggest that occupation during this period was restricted to hamlets and villages, much of which may be beneath modern settlements.
