Roman Earthwork 540m W of Y Pigwn is a Roman fort situated in Wales on bedrock of Ludlow Rocks, a formation of mudstone, siltstone and sandstone laid down in the Ludlow period. The earthwork survives as an archaeological monument protected by Cadw under reference CM194, preserving the defensive infrastructure of the Roman military presence in this region.
Roman forts of this type typically comprised a rectangular plan enclosed by substantial ramparts and ditches, designed to accommodate a garrison and supplies whilst maintaining control of the surrounding territory. The underlying geology of mudstone and siltstone would have provided stable ground for construction, though the softer nature of these rocks required careful foundation work and drainage management during the fort's operational period.
The monument's survival as visible earthworks reflects the low-lying topography of its location and the depth of deposit that has accumulated since the Roman withdrawal from Wales in the early fifth century. The site remains an important record of Roman military organisation in the Welsh landscape, offering evidence of the strategic deployment of forces across the province during the occupation period.
