Offa's Dyke: Chirk Park Section is an early medieval linear earthwork extending 340 metres north-east from Home Farm near Chirk in Wales. Constructed in the 8th century, the dyke represents one of the most substantial engineering projects of Anglo-Saxon Britain, built as a frontier work between the Kingdom of Mercia and the Welsh principalities. This section remains a prominent landscape feature, its ridge and ditch configuration still clearly visible across the terrain.
The monument sits upon bedrock of the Millstone Grit Group, a sequence of mudstones, siltstones and sandstones formed during the Namurian geological period. This solid foundation provided stable ground for the earthwork's construction and has enabled the dyke to survive over twelve centuries of erosion and agricultural use.
The Chirk Park section is protected under the care and control of Cadw, the Welsh Historic Monuments service, under reference DE198. This statutory protection ensures the ongoing conservation of this significant early medieval frontier marker, preserving it as a key testimony to the complex political geography and engineering capabilities of early medieval Britain.
