In September 2019 the Clwyd-Powys Archaeological Trust conducted a heritage assessment in connection with proposals for a change of use of land at Gledrid Farm, St Martin's, Shropshire, to accommodate ten holiday cabins in an area which is currently agricultural land. The assessment considered all designated and registered heritage assets within 1km of the Development Area, and non-designated assets within 250m. The Development Area lies within the buffer zone surrounding the Pontcysyllte Aqueduct and Canal World Heritage Site (WHS), and also within a short distance of the scheduled Roman military site at Rhyn Park and the scheduled section of the Ellesmere Canal, which is also part of the WHS. Fieldwork undertaken as part of the assessment determined that owing to the topography and existing screening provided by structures and mature trees the Development Area has very restricted intervisibility with heritage assets within the study area. The visual impact on the World Heritage Site, the Ellesmere Canal and the WHS buffer zone is considered to be negligible, while the assessment has determined that the Development Area will have no impact on the settings for the Roman military site at Rhyn Park. Negligible visual impacts have also been identified for two non-designated heritage assets, while a further two might be subject to minor impacts.
