As part of the Arfordir Project, Dyfed Archaeological Trust investigated the eroding medieval settlement at St Ishmael, Carmarthenshire. Excavations in 2011 focused on a stone-built house (Building 2) with paved entrances, beaten earth floors and associated features, alongside evidence for timber structures and pits nearby. Pottery finds suggest occupation between the late 12th and 14th centuries, with decline by the 15th century. The site, already heavily damaged by coastal erosion, continues to be lost at an estimated 0.15–0.30m a year, though important archaeological deposits still survive beneath the dunes.
