Around Wrexham, Wat’s Dyke remains an important monument but heavily damaged by agricultural, industrial and construction activities. Running c. 38 miles from Basingwerk to Maesbury, it is a monument often overshadowed by its larger neighbour: Offa’s Dyke. Excavations at Gobowen suggest that it is later than Offa’s Dyke: a Mercian construction of the early 9th century AD.
At Pandy, as part of a recent field trip exploring the industrial and post-industrial uses of the landscape, I encountered a section that runs from near the railway line across the fields towards what is now the A483, before it enters into what is now the suburbs of Wrexham. See my previous discussions of it at this location here, and nearby at Erddig here and here.
Fox, writing in Archaeologia Cambrensis in 1934, has this to say about the section.
Wat’s Dyke begins again 50 yards to the S. of the “Y” road junction, near Pandy Farm. (From this point northwards to the road, there is a mere hedge bank). The construction of the railway obscured the topography, but it is clear that the terminal point is exactly what was the head of a lateral (and doubtless boggy and thickly wooded) ravine opening northwards down Wilderness Wood to the main river (see Fig. 26, 5, a). From the very beginning, the Dyke was straightly aligned (Type I) to the 300ft contour, 620 years away, and was throughout on a large scale with a broad W. ditch present-day irregularities are due to destruction and levelling.
While the bank is denuded, it is clearly larger than any later field boundary, and straight-aligned with extensive views westwards. Moreover, nothing more than a wide depression running west of the bank, it is evident that a large ditch once existed on the dyke at this location.
In this position, Wat’s Dyke is not following the top of a ridge or ravine. Instead, it is running as straight as possible over relatively flat ground in order to navigate between the Alyn and the Clywedog rivers. To the south, it crosses the Clywedog before following the eastern ridge of the Black Brook past Erddig Hall. To the north, it crosses the Alyn and incorporates the earthworks of Caer Alyn hillfort.
We also encountered an inquisitive horse!
