The 2022-23 issue of Iarmhí: Journal of the Westmeath Archaeological and Historical Society, features an article on the archaeological discoveries made in advance of the construction of the N52 Cloghan to Billistown Realignment Scheme (Phase 2), to the south-west of the village of Delvin.
Kerri Cleary and Ian Russell detail the excavations undertaken by ACSU at eight locations between October and November 2018. These include new prehistoric and early medieval sites, as well as additional information about a previously known enclosure and land divisions depicted on historic mapping. In the townlands of Reynella and Crosserdree, later Neolithic and earlier Bronze Age occupation of the landscape was evidenced by clusters of pits, post/stake-holes, occupation deposits and hearths or fireplaces, often with no clear structural patterns or ground plans. In the townland of Williamstown (Rochford), two pits set 1.80 m apart were related to the production of charcoal in the Iron Age, while a similar site in the townland of Reynella was in use during the early medieval period, perhaps sometime in the mid-fifth to mid-seventh century AD. Following geophysical survey by Target Archaeological Geophysics, part of an extensive field system associated with a circular enclosure (Record of Monuments and Places No. WM013-095) in the townland of Ballygillin was also excavated.
