  • We carried out excavations at Rathfarnham Castle, a fortified house constructed in 1583 by Archbishop Adam Loftus, in 2014. An astonishing collection of 17,500 artefacts dating to the very end of the 17th century was recovered. We also carried out archaeological work in 2016 and 2017, with additional findings.

  • A fascinating multi-period site was excavated at Brighton Road in Foxrock, Dublin 18. A natural spring provided the setting for Middle and Late Bronze Age (1400 BC to 900 BC) activity in the form of wells and fulachtai fiadh. In the mid-7th century AD a large non-domestic rectangular structure was erected on the fulacht fiadh mound. It is unique in the Irish archaeological record and may have been an early Christian shrine or baptistery, dedicated perhaps to a Munster saint such as Cian. In the mid-9th century the structure was intentionally dismantled and burnt down, which may be linked to the expansion of the ecclesiastical site at Tully.

    The final report is available here.

  • The archaeological site at Butchersarms has been under archaeological testing and excavation from March 2023 to December 2024, and works are projected to continue into 2025.

    The excavated evidence dates broadly to the early medieval period/first millennium AD, though Late Bronze Age activity is also present. Two concentric enclosures 50m and 115m diameter in the eastern portion of the site contain a burial mound with c. 300 inhumations and a possible rectangular structure with rounded corners. This is in turn enclosed by a sub-circular enclosure c. 450m forming the parish boundary of Kilmainham dating to at least the late medieval period century, which encompasses a large number of pits filled with animal bone.

    This report concludes that the three concentric enclosures may represent a non-ecclesiastical cemetery/assembly site dating approximately to the fourth to ninth centuries AD possibly predating the nearby ecclesiastical site of Cell Maighnean. The site was occupied by a Viking camp in the mid-ninth century and there are numerous artefacts from this phase, including the only two Northumbrian styca (coins) found on the island of Ireland, three lead weights, two Vikingtype spearheads, keys, and decorated copper alloy objects. Of particular interest is the evidence that the pre-existing burial ground was reused by the Vikings in the ninth century for burial.

    The preliminary archaeological results of the archaeological excavations in 2024 are set out in Volume 1 here and Volume 2 here.

  • The excavation at Clonard on the outskirts of Balbriggan, Co. Dublin uncovered an intriguing prehistoric landscape possibly informed and influenced by the wetlands located on the site and by an exceptionally early Mesolithic pathway that survived as a route through this landscape for millennia. Ceremonial and burial monuments from throughout the prehistoric period were uncovered between the pathway and the wetlands along with features associated with the exploitation of the natural resources of this environment. A pollen core of organic material from one of the wetland pools revealed a snapshot of the local environment throughout the Neolithic period.

  • Three Early Bronze Age burnt mounds and associated features were excavated at the edge of a former wetland pool on a site off Glenamuck Road, near Kiltiernan in 2021. The edge of a burnt spread was also identified at the limit of excavation suggesting a fourth burnt mound site may exist beyond the site boundary to the south. Several sherds of decorated Beaker pottery were retrieved from the fills associated with one of the burnt mounds and an adjacent pit. As this material predates the burnt mound by over 400 years it is likely to be ex situ, but it hints at earlier activity in the vicinity of the wetlands the burnt mounds were associated with.

    The results of the desktop assessment and programme of monitoring are presented within a report conducted by Archaeology Plan in 2021.

  • A programme of archaeological monitoring and subsequent excavation took place during Phase 1 of a site in Kiltiernan, Co. Dublin. Three burnt mound sites and several small isolated archaeological features were identified on the site. They were situated on the east of a former wetland area, which had subsequently become a small bog. Two of the burnt mound sites had surviving burnt spreads and two had surviving structural elements in the form of fence-lines, windbreaks, or shelters.

    Prehistoric ceramics and flint tools were also retrieved from two of the burnt mound sites. Interestingly, despite ceramics rarely being retrieved from burnt mound sites, some was previously identified at another burnt mound site near Kiltiernan at Glenamuck North, while the other sites where this has occurred in Co. Dublin are all within 3.5km of the site. This may indicate a specific activity being carried out at these fulacht fiadh sites in South Dublin, though further analysis of the ceramics and radiocarbon dating is required.

    Another truncated pit, possibly the base of a trough of a fourth burnt mound site, was identified on the western side of the wetland. Though only the base of the feature survived, it also contained prehistoric ceramics.

    The results of this Phase 1 excavation can be found here.

  • Archaeological monitoring at Clonsilla in 2019 exposed the remains of a medieval field system and a very unusual feature: rows of pits in one of the medieval fields. Each pit was identical (1.60m by 0.50m and 0.35m deep) and arranged in rows 6m apart, and the pits in each row were also spaced 6m apart, and the pits extended over an area measuring at least 80m by 50m. The pits contained few artefacts other than small sherds of medieval pottery. This report defines the finding as a pitfield, and compares it to other pitfields in Roscommon. Various possible functions for the pitfield are put forward, including that they were excavated for military or agricultural reasons.

    The preliminary report is available here.

  • A programme of archaeological monitoring and excavation was carried out on the site of a proposed school in Mooretown, Swords, Co. Dublin from April to June 2019. The most significant archaeological feature encountered was a Late Neolithic pit containing the remains
    of a Grooved Ware vessel.

  • Archaeology Plan have been carrying out excavations near Shankill, Co. Dublin since 2020 in advance of a large-scale residential development. The excavations to date have uncovered an intriguing prehistoric landscape positioned in the narrow coastal plain north of Bray.

    While some Early Neolithic activity was noted on the site the earliest substantial archaeology was an arc of Late Neolithic post-pits, which contained structured deposits of broken Grooved Ware ceramics, worked flint and a large quantity of flint debitage.

    A number of possible structures and occupation layers were identified nearby that were associated with a large quantity of Beaker ceramics suggesting a Chalcolithic or Early Bronze Age settlement was present in the lower-lying western portion of the site. An Early Bronze Age cremation urn and associated food vessel, both heavily decorated, were excavated on the ridge of slightly higher ground to the east of the settlement. A number of other pits containing small quantities of Beaker ceramics were identified in the vicinity of the urns indicating activity contemporaneous to the settlement to the west was taking place here also.

    A large settlement enclosure, possibly dating to the Late Bronze Age based on the ceramic assemblage associated with it, was excavated in the north of the site. While the interior of the enclosure was scarped and little survived, quantities of ceramic, flint, ground stone tools, animal bone and charcoal were present within the ditch defining the enclosure.

    To the south of this a probable Iron Age settlement was uncovered associated with two structures and two ring-ditches. A late prehistoric field system also appears to have been associated with the settlement. A number of glass beads and purple glass bangle fragments were retrieved from one of the ring-ditches along with a cache of sling-stones, suggesting the settlement had contacts with Iron Age Britain to the east. Sixteen metalworking furnaces have been excavated on the site to date, which may also be related to this phase of activity on the site. Two cereal drying kilns were also uncovered in the immediate vicinity of the settlement and are likely to be contemporary.

    A series of metalled surfaces were identified across the site, mainly on the higher ground to the east. Some of these appear to be associated with the late prehistoric settlement while others date to the early medieval period. Twenty-one cereal drying kilns have also been excavated, and while some may be associated with the late prehistoric settlement on the site, a number of complexes of intercutting kilns were identified post-dating the late prehistoric field system, which are likely to be early medieval in date. One of the kilns dated to the 12th-14 century based on associated ceramics. A large double-ditched enclosure, possibly of early medieval date, was identified on the site during previous testing and geophysics and was preserved in situ within the development.

    Post-excavation analyses are underway and a suite of radiocarbon dates are being obtained for the site. Monitoring is to continue on the site next year.

  • The archaeological excavation of an early medieval settlement site evolving over a number of phases was uncovered at Alexander Reid, Navan, Co. Meath. A series of eleven kilns were uncovered associated with the various phases of the ringfort along with four structures.

    During the early post-medieval period the site was reused as a burial site for a short period.

    The findings are presented in two reports:

    Alexander Reid Preliminary Report Site A Volume.

    Alexander Reid Preliminary Report Site D Volume 1.

    Alexander Reid Preliminary Report Site D Volume 2.

    The site was revisited in 2022 and the archaeological excavation was an extension of the 2016 site.

    A cluster of features relating to at least two phases of cereal processing were excavated on a low rise overlooking a late prehistoric and early medieval settlement site around 100m to the northwest, which was excavated in 2016. A ditch, presumably part of the early medieval field system, was also uncovered, with one of the kilns post-dating the ditch and one predating it. An additional kiln was excavated east of the ditch.

    A small sub-oval structure defined by stake-holes was excavated adjacent to the kilns along with two curving slot trenches. These appear to represent fence-lines, possibly surrounding a fire-pit that was located within the area partially sheltered by the slot trenches, or defining an approach to the kiln area.

    A large shallow pit with a metalled base was uncovered nearby, possibly associated with the cereal processing. A later paved surface partially survived within the pit.

    These features were an extension of the archaeological site excavated in 2016 and demonstrate that cereal processing extended beyond that settlement up slope to the south.

  • The excavation at Dundalk took place on Clanbrassil Street, Church Street, Bridge Street and Linenhall Street in Dundalk town centre. The medieval street surfaces were identified, along with medieval structures constructed of large masonry walls. One of these, in front of St Nicholas’ Church, was identified as the remains of a tower house depicted on this site on a map of the town of Dundalk in 1675. The remains of another medieval tower house, Howths Castle, was identified on Clanbrassil Street in front of the Diamond Buildings, and a medieval wooden building was excavated on Church Street. Very rich organic deposits were identified throughout the excavated areas, and contained very large amounts of animal bone and medieval pottery. The pottery is Dundalk Ware, and was particularly dense on Bridge Street not far from the location of a medieval pottery kiln excavated in 1997. A significant assemblage of late twelfth to early thirteenth century leather shoes, knife sheaths and a decorated leather scabbard was also recovered. Other artefacts included carved bone and wooden objects, metal objects, and a decorated slate inscribed with a mythical creature. High status 16th to 17th century drinking glasses were also recovered on Church Street, near the location of the tower house.

  • Archaeological monitoring and excavation took place at the site of the Black Millers Hill residential development in two phases and under two separate archaeological licences.

    The excavations were done in advance of a housing development that was built in two phases from 2018-2021 and revealed archaeology dating from the Early Neolithic up to the medieval period. The archaeology reflects its location at the edge of the significant prehistoric grassland landscape of the Curragh, and later at the edge of the ecclesiastical settlement of Kildare.

    The archaeology uncovered included an Early Neolithic pit cluster, Chalcolithic and Early Bronze Age burnt mounds, and an Early Bronze Age kiln. Additional Bronze Age features were also identified indicating this was a time of increased activity in the vicinity of the Curragh. A small Iron Age enclosure surrounding a rectangular structure was also identified, along with a contemporary ironworking furnace. 

    Later activity included two large 11th-13th century cereal-drying kilns, one of which was adjacent to a four-post raised granary structure. The kiln and granary were within a small enclosure. The kilns were not related to any nearby settlement and likely belonged to the ecclesiastical settlement at Kildare, demonstrating the control that establishment had over its hinterland.

  • A substantial early medieval cemetery settlement site was identified to the west of Dunshaughlin in 2010. The central enclosure, including the burial ground, was preserved in situ. The remainder of the settlement was excavated in 2018 and 2019, which uncovered numerous associated ditched enclosures, a large iron production site, multiple cereal-drying kilns and a number of structures.

    In the lower-lying lands to the south of the early medieval settlement a number of prehistoric features were uncovered including a cremation pyre site and cremation pit, a second possible pyre site, two fulacht fiadh sites, and two prehistoric pit clusters.

    Post-excavation analysis of the site is ongoing, including an important analysis of the metallurgical waste from the iron production on the site.

  • A complex fulacht fiadh site was excavated at Knockaphunta, south of Castlebar, Co. Mayo in 2016. The site was used over an extended period of time from the Middle to Late Bronze Age. A water management system was uncovered along with four troughs, which were used sequentially.

  • A Late Bronze Age burnt mound site was excavated on the northern side of the River Finn in Stranorlar, Co. Donegal in advance of the construction of a school in August 2020. A burnt spread sealed a number of features including a partially stone lined sub-rectangular trough.

    Cut features were also uncovered in the vicinity of the trough. The cut features were truncated and compressed by the overlying concreted burnt spread. Based on the placement of the features they appeared to represent the remains of a structure associated with the burnt mound site. A central feature may be the base of a larger central posthole, or a central pit within the structure. Two hypothetical layouts for structure are suggested, one a roofed structure with central posthole, and the other a fenced-off work area. 

    A small quantity of bone, both burnt and unburnt, and a large granite grinding stone, the upper stone of a quern stone, were retrieved from the site. The bone suggests some level of consumption of meat or processing of animal products (hide, bone etc.) was taking place at the site, while the quern stone suggests grain processing was taking place at the site or nearby. The grinding stone was later reused as an anvil, with these artefacts associated with tool production, pottery manufacture, plant processing and food preparation in the prehistoric period. Given the lack of lithics or ceramics from the site the latter two are more likely in this instance, and the anvil may have been used in antler or bone working, in marrow extraction, or it may have been used in processing relating to textile production.
