Following submission of a planning application for the construction of a new garage and associated access road on land at Fairfield Lodge, Cartmel, Cumbria a condition was placed on the Scheduled Monument consent for an archaeological watching brief on the associated groundworks. Greenlane Archaeology carried out the work in July and August 2021. A preceding desk-based assessment had shown that the site formed part of a single field to the south of Fairfield Lodge since at least the early 19th century, and had seen very little change. An archaeological evaluation was carried out prior to the submission of the planning application comprising the excavation of two trenches. The northernmost of these (Trench 2) revealed no archaeological features, although a collection of medieval pottery was recovered from the topsoil. The south-western trench (Trench 1) revealed a range of features and deposits, including an apparently deliberate raised area of redeposited clay and gravel, either side of which was a deposit containing some slag. The watching brief revealed a range of additional features, all of them probably or definitely post-medieval in date. These comprised a substantial ditch following the line of the boundary to the north, which probably represented a ha-ha, and a linear ditch, most likely a former field boundary. Service trenches for both gas and electricity were also present, cutting through earlier deposits, and the raised area of redeposited clay and gravel was found to have been truncated outside of the area of the original evaluation trench. More significant was a layer of redeposited material or subsoil in the area of the new driveway, which contained a collection of medieval pottery and an assemblage of ironworking residue. Analysis of this confirmed it as smelting waste from the bloomery process, which had been reprocessed from its original location, and it is another example of such material recovered from the north-west part of the priory precinct. Other finds of interest include two unusual marked clay tobacco pipe stems.
