Westmeath ISSUE 3: Eachtra Journal - ISSN 2009-2237 1 Non-Technical Summary This report details the results of archaeological excavations carried out at Monganstown townland, along the line of the N6 realignment between Kinnegad and Kilbeggan (Figure 1). Situated approxi- mately 2 km west of Kinnegad, the site is one of fourteen new archaeological sites identified during test excavations carried out in 2004. Following the identification of archaeological remains in situ during the testing phase, it was recommended that preservation by record would be required. The main concentration of archaeological features was confined to an area of approximately 15 m2 and was excavated under ministerial order A001/001. Evidence was recovered showing the existence of early medieval charcoal production pits, and Iron Age ironworking features, as well as other possible smelting and smithing furnaces close by. Several other pits were excavated,
