As part of proposals for the construction of an extension to the north side of the nave of the Priory Church of St Mary and St Michael, Cartmel, Cumbria, Greenlane Archaeology carried out an archaeological evaluation. This was primarily carried out inside the footprint of the proposed extension and included the excavation of three trenches within this area. A fourth trench was excavated to the north where it is intended some extant grave covers would be moved in order to accommodate the new extension, and a fifth trench was excavated alongside part of the footpath where the ground level might be lowered in order to improve accessibility. The site's history is dominated by the presence of the medieval Priory Church, which originally formed part of the Augustinian Cartmel Priory, which was established in the late 12th century. The documentary history of the priory in the medieval period is not detailed, although a postulated understanding of the development and arrangement of the site has been established through various pieces of evidence. Significantly it is thought that the cloister was moved from the south side of the church to the north in the 14th century. The church is the only part of the priory that survived the Dissolution to the present day and there is considerable documentary evidence for renovation and alterations to it from the early 17th century onwards, with a particularly large programme of work in the late 19th century. The evaluation revealed features and deposits of archaeological interest in all five trenches, with deep, vertically-sided, linear features present in Trenches 1 and 4 and shallower linear features in Trenches 1, 2 and 5. In Trench 3 a substantial deposit of dumped demolition material, containing large amounts of human bone, was also found, and in Trench 4 a shallow pit containing a large amount of domestic rubbish, essentially the remains of a midden, of late 18th or early 19th century date, was found. Two residual pieces of medieval pottery and 10 fragments of floor tile of probable medieval date were recovered, but all of the features and deposits encountered were apparently post-medieval in date. The form of the deep vertically-sided features in Trenches 1 and 4 is suggestive of robbed out walls. In the latter case the dating evidence shows that this must have taken place in the late 18th or early 19th century, but it is plausible that the walls were part of the medieval priory. The shallower linear features were typ...
