Offa's Dyke at Upperton Farm is a section of the linear earthwork constructed during the reign of King Offa of Mercia in the late eighth century, forming a boundary between the Anglo-Saxon kingdom of Mercia and Wales. The monument comprises two distinct segments extending southward from Yazor in Herefordshire, measuring approximately 195 yards and 370 yards respectively. The dyke displays the characteristic form of a substantial bank with an external ditch, representing one of the most significant defensive and territorial features of early medieval Britain. This section of the monument survives as an upstanding earthwork and remains an important witness to Anglo-Saxon frontier administration and engineering during the Mercian period.
