Saxon ForumFilling the holes in Offa's Dyke

Admin (Admin)
I've been trying to map out Offa's Dyke from its starting point near Chepstow on the Severn to Prestatyn on the Dee Estuary.

Sadly it was not to be the uninterrupted coast to coast linear feature I wanted.

The stretch from Treuddyn to Prestatyn is very tenuous. With Wat's dyke to the east being a more continuous and linear feature.

Maybe a later redrawing of the boundary between Mercia and Wales?

It's also apparent that the feature follows the contours of the landscape so well that some breaks along cliff edges are intentional.

The earthwork in also interrupted by iron age hillforts and Roman camps. Maybe the theory that Offa's dyke is older than early medieval holds water?

Anyone know of any good resources to help me fill the gaps in Offa's Dyke?

The wideness of the river formed a natural boundary and perhaps only a wooded palisade was constructed?

Wat's Dyke runs close to Offa's northern section.
