Offa's Dyke Section N & S of the Circle on Holywell Racecourse is an Early Medieval linear earthwork forming part of the longer defensive frontier constructed under King Offa of Mercia during the late eighth century. The monument comprises a substantial bank and ditch system that survives in two sections flanking a circular feature on the racecourse at Holywell in Flintshire. The dyke represents one of the most significant engineering projects of the Anglo-Saxon period, constructed to mark and defend the border between Mercia and the Welsh kingdoms of the period. The associated circular feature visible within this section may relate to Bronze Age activity on the site, though the primary archaeological interest lies in the preserved Early Medieval linear earthwork and its role in the broader Offa's Dyke frontier system.
