Although many definitions of archaeological excavation refer to the total ‘destruction’ of an archaeological site, a more accurate description of the process is ‘deconstruction’. In other words, a site is deconstructed or taken apart in a controlled and scientific manner in order to understand its genesis and morphology.

Archaeological excavation involves the systematic uncovering of archaeological remains through the removal of the deposits of soil and the other material covering them and accompanying them. During the ‘deconstruction’ of a site, the information contained in the archaeological deposits is preserved by record. Each deposit is meticulously excavated and recorded: each change in soil colour and/or texture is noted, samples are taken to be analysed for any organic remains, and finds recorded as to exactly where they were found.Archaeological excavation remains the only way to check the reliability of surface data, confirm the accuracy of geophysical survey results, and actually see what remains of these sites. The aim of archaeological excavation is to preserve through record the archaeological deposits that are being deconstructed through excavation. Ideally this means that should you so want to you could recreate the site.




As part of the archaeological resolution phase of the M3, all sites will be subject to two phases of topsoil assessment in advance of excavation. Topsoil assessment involves the systematic metal detecting and systematic field walking of the exposed topsoil in order to assess the artefact bearing potential of the agriculturally disturbed topsoil.

Following the completion of the topsoil assessment at each site, the results will be reported to the National Monuments Section of the DoEHLG and approval sought for the next phase of archaeological resolution, excavation. At some sites, which are determined to have a low archaeological potential for artifact retrieval from the topsoil, the topsoil is removed mechanically. A mechanical excavator using a flat bladed (i.e. toothless bucket) is used to remove the topsoil carefully in layers under the constant supervision of a qualified archaeologist in order to uncover the archaeological site. At sites where a high potential for artifact retrieval is identified a suitable methodology for topsoil removal is proposed. This usually involves hand excavation of the topsoil.

A large cutting will be opened around all archaeological features identified during testing. In the event of additional features being exposed the cuttings will be enlarged as necessary. All previously recorded archaeological features and newly exposed features will be cleaned and hand excavated. All features will be recorded (by plan, photographs, levels, feature sheets etc.) using multi-context planning.

Cooksland 4 Stone spread Stone building debris Early Modern
Cooksland 2 Burnt mound Burnt spread Bronze Age A spread of burnt stone overlying a trough. This was filled with burnt stone and contained a badly decayed timber base and four stakeholes which would have held the timber sides of the trough.
Cooksland 1 Industrial Possible charcoal manufacturing kiln Possible Medieval The single pit identified during testing phase was relocated during the resolution phase. No further archaeological features were identified.
Roestown 2 Settlement complex Large ditched enclosure complex split by existing N3 Early Medieval A series of successive early medieval enclosures, including a souterrain and field systems, beginning in the 7th century and continuing into the 11th century with limited occupation into the 13th century.
Roestown 3 Vernacular building Stone building foundations Early Modern A number of features identified as the foundations of an early modern stone wall.
Roestown 1 Burnt mound Pits with burnt stone fills Bronze Age A spread of burnt mound material overlying two troughs and a large circular pit. A number of stakeholes to the north of these features did not form any coherent plan. Finds included a flint arrowhead and scraper.
Garretstown 2 Possible Settlement/Industrial Industrial activity, pits and ditches adjacent moated site. Medieval Two main phases of activity have been identified. In the absence of any diagnostic finds the dating of the site remains provisional until radiocarbon and OSL dates have been returned. The first phase of the site is represented by two large ringditches (one circular, one sub-circular) and perhaps a number of smaller circular ditch features. This phase is provisionally dated to the Bronze Age. The second phase of the site is represented by a series of large linear ditches and a large sub-rectangular enclosure with a massive ditch extending and lying mainly outside the landtake. This phase is provisionally dated to the early medieval period. Approximately 10 corn-drying kilns were excavated across the site and it is assumed that they also belong to the early medieval period.
Garretstown 1 Possible burial site & possible settlement Possible cremation pits and hearth, pit and posthole Possible Prehistoric Features found to be modern and / or natural in origin.
Berrillstown 2 Burnt mound Pit and burnt spread Bronze Age A small number of sub-circular pits, stakeholes and small curvilinear features. The pits were filled with burnt stones and charcoal-rich soils and may represent the remains of a small burnt mound.
Berrillstown 1 Burial site Probable cremation pits adjacent a ring ditch Bronze Age A large scatter of pits and a corn-drying kiln concentrated around the edge of a ringditch, which lies immediately outside the landtake. One artefact was recovered – a lignite bracelet fragment. These preliminary findings seem to indicate an early medieval date.
Clowanstown 3 Burnt mound Pit and burnt spread Bronze Age Two shallow oval hearths were recorded, one of which was located in an earlier tree bowl. No further features were found to be related.
Clowanstown 2 Burnt mound Pits and small burnt spreads Bronze Age Four burnt spreads, nine pits, a sub-circular hearth and a shallow field ditch. Finds include a hollow-based chert arrowhead and core, two scrapers and flint debris, suggesting flint / chert working on site.
Clowanstown 1 Burnt mound Burnt mounds Bronze Age A number of phases of activity were identified. The earliest dates to the late Mesolithic or very early Neolithic period, in the form of timber platforms, pits, at least two woven fish baskets and Bann flakes, located on the edge of what would have been a small lake. This lake later developed as a raised bog, on which three mounds were constructed during the early Neolithic period. Deliberately constructed layers within the mounds contained cremation deposits, Early Neolithic carinated bowls, worked wooden vessels, polished stone axes and stone pendants. A fourth mound was constructed at a later date and is characteristic of a burnt mound or fulacht fiadh.
