This report details the results of the archaeological excavation of Ballytrust 1 in advance of the proposed N55 Realignment Scheme, Co. Cavan (Figures 1-2). The site was identified during archaeological testing Stage (i) of the proposed N55 Realignment Scheme, Co. Cavan and was carried out under the supervision of Jon Stirland (Senior Archaeologist) of Archaeological Consultancy Services Unit. It was carried out between the 8th August and 19st August 2016 under licence numbers 16E0169 & 16E170 issued by the Department of Culture, Heritage & the Gaeltacht in consultation with the National Museum of Ireland. The excavation was carried out by Mr. Derek Gallagher between 3rd November ? 16th November 2016 under licence 16E0527 issued by the Department of Culture, Heritage & the Gaeltacht, issued in consultation with the National Museum of Ireland. Ballytrust 1 (Figures 1 & 2) was located at the bottom of a low drumlin hill beside a small stream. The field was located to the west of the current N55, at the southern end of the N55 Phase 2 road re-alignment. The site consisted of a series of burnt spreads running along the bottom of the hill in line with the small stream demarcating the base of the hill and the beginning of the rise of the far hill to the west. There was a degree of modern disturbance along the line of the stream, probably as a result of modern drainage and there was some made up ground (circa 1m wide) directly along the line of the stream. It is likely that the burnt stone spreads identified in this excavation experienced disturbance in the past. There were seven small burnt stone spreads (C03-C09) running along the base of the stream in a north ? south direction. These varied in size and are detailed below. Under these burnt stone spreads five troughs were identified (C14, C15, C18, C19 & C23) and five post holes (C20-C22, C37 & C38). The troughs also varied in size and it is likely that the site represents a series of activities over a period of time along the banks of this stream. Charcoal samples were recovered from the basal fills of three of the troughs. A sample of charcoal (S#11, C25) recovered from the basal fill of the trough C23 was examined by wood specialist Ellen O?Carroll, identified as piunus and recommended for radiocarbon dating. The sample contained 0.1g of charcoal and returned a date of 2203-2033 cal BC (3725 +/- 30 BP) indicating the trough was in use during the Early Bronze Age. A second sample (S#12, C28) recovered from the basal fil of trough C18 was identified as hazel by Ellen O?Carroll. This sample contained 0.5g of charcoal and returned a date of 2458-2199 cal BC (3835 +/- 35) indicating a broadly contemporary date. The third sample (S#20, C31) from the basal fill of trough C14 was identified as alder, contained 0.2g of charcoal and returned a date of 2136 ? 1921 cal BC (3835 +/- 35). No other post-excavation analysis was undertaken for this site and no finds were recovered from the archaeological features. The charcoal identified at this site was most likely used as firewood as well as post material. Hazel dominated the burnt mound spreads, troughs and pits while oak was more prevalent in the posthole fill (C33). A split alder plank and a post were used in the construction of one trough (C14). Lesser counts of blackthorn/cherry and willow were also identified. Charcoal analysis from burnt mound/fulacht fiadh sites generally represent the local woodland which was being exploited as inhabitants would gather firewood close by to their site. The results indicate selection of wood from hazel and oak woodlands as well as scrubland areas of blackthorn and cherry. Alder and willow trees are adapted to a wetter growing environment and as such may have been collected from a wetland area or riverside close to the site. Four fulachta¡ fia have been excavated as part of the current scheme and include Ballytrust 2 located 114m to the southeast and further north east along the scheme Garrymore 2 and Garrymore 3. Similar dates (2456 -2142 cal BC and 2471 ? 2214 cal BC) were returned for Ballytrust 2 suggesting Early Bronze Age activity in this townland, where the natural resources in the landscape were utilised.
