The course of Rowe Ditch follows the hedge on the far-side of these fields to the east of Staunton and below Shobdon. The ditch is almost certainly Anglo-Saxon in origin and lies along a straight line accross the Arrow valley, it's about 4km long and was probably put up to define an early frontier and also offer a causeway across the flood plain of the river Arrow, which still regularly floods to this day. The ditch is on the west side with the bank behind it as is the case with other nearby dykes. In places the width is up to 15 meters. The ditch originaly ran further up the valley towards Shobdon. Like Ditch Bank, several miles to the west near New Radnor, the dyke is sited to the west end of a valley, apparently to protect high quality agricultural land. Excavations at Leen farm revealed that the dyke was definitely built after the Roman period. A cropmark enclosure dated to that time was found to underlie the dyke proving the dyke to be later. It is most likely to be an Anglo-Saxon frontier work from the 6th century, although it is not historicaly referenced until it appears in a 10th century document.
