Llanrhaeadr-ym-Mochnant Crop Marks W of Meusydd Smithy is a prehistoric enclosure located in the parish of Llanrhaeadr-ym-Mochnant in Wales. The monument lies on bedrock composed of Caradoc rocks, an undifferentiated sequence of mudstone, siltstone and sandstone formed during the Caradocian period. These sedimentary deposits provide the geological foundation across this upland landscape.
The enclosure is identified through crop marks visible from above, indicating buried archaeological features that alter soil moisture retention and plant growth patterns. This non-invasive form of detection reveals the monument's presence without excavation, a common method for identifying prehistoric settlements and ritual sites in areas where surface remains are minimal or disguised by later land use.
The monument is protected by Cadw, the Welsh Heritage Monuments service, under the reference DE220, recognising its archaeological and cultural significance. The site's survival as a recorded heritage asset preserves evidence of human settlement and land use during prehistoric periods across this part of mid-Wales, contributing to understanding of early communities in the region.
