The site had previously been investigated archaeologically in 1983 and 1984 as part of an investigative programme of cropmark complexes around Four Crosses, when three ring ditches forming part of an extensive barrow cemetery of probable Bronze Age date were excavated within the site. In response to a planning consultation for development of the site, a programme of geophysics and archaeological evaluation was undertaken in 2002 and 2003 respectively. The CA excavation was subsequently carried out as a condition of planning consent. The excavation revealed numerous features dating from the Neolithic to post-medieval period. One pit produced several large potsherds of late Neolithic date. Eleven ring ditches and the southern half of a barrow mound, which were part of the barrow cemetery, were excavated. The barrow mound was shown to have been constructed in two phases, with a small primary mound being replaced by a larger secondary mound. Graves were revealed within several of the ring ditches. Other features included several undated pit alignments and two Romano-British enclosures and field system. Evidence for Roman metalworking was also uncovered, comprising postholes and pits with copper-smelting waste including slag, daub superstructure and a fragment of block tuyère. A small cemetery of probable Roman date was also excavated. 3 Land at Domgay Lane, Four Crosses, Powys: Post-Excavation Assessment and Updated Project Design © Cotswold Archaeology This document presents a quantification and assessment of the significance of the evidence recovered from the fieldwork. It considers the evidence collectively in its local, regional and national context, and presents an updated project design for a programme of post- excavation analysis to bring the results to appropriate publication. 4 Land at Domgay Lane, Four Crosses, Powys: Post-Excavation Assessment and Updated Project Design © Cotswold Archaeology 1. INTRODUCTION 1.1 Between October 2004 and October 2006 Cotswold Archaeology (CA) carried out an archaeological excavation and watching brief on land at Domgay Lane, Four Crosses, Powys (centred on NGR: SJ 2707 1878; Fig. 1). The work was undertaken at the request of Waterman CPM Limited, and subsequently The Environmental Dimension Partnership (EDP), on behalf of Jennings Homes (now part of David McClean Homes) in accordance with a Design Brief for Archaeological Excavation prepared by Clwyd Powys Archaeological Trust (CPAT) Curatorial Section (2004), archaeological advisors to the Local Planning Authority, and with a subsequent detailed Written Scheme of Investigation (WSI) produced by CA (2004). The fieldwork also followed the Standard and Guidance for Archaeological Field Evaluation, the Standard and Guidance for Archaeological Excavation and the Standard and Guidance for an Archaeological Watching Brief issued by the Institute of Field Archaeologists (1999), and was guided by the Management of Archaeological Projects II (EH 1991). Location 1.2 The site comprises an area of approximately 2.4ha on the north-eastern side of the village of Four Crosses (Figs 1 and 2). The site is located towards the western extent of a low gravel terrace (c. 60m AOD) by the confluence of the Rivers Severn and Vyrnwy. The flood plain of these rivers extends for at least 2km to the north, east and south of the site, while to the west
