Archaeological investigations stemming from the development of the Grange Castle International Business Park near Clondalkin, Dublin 22, have uncovered a variety of features, notably a Bronze Age ring barrow.
The ring barrow was excavated between July and September 2000, under the direction of Ian Doyle, in Kilmahuddrick townland. The site, which was detected during geophysical survey and follow-up archaeological assessment, was excavated prior to the commencement of construction of a biotechnology campus in the Grange Castle International Business Park. The project was managed by Arup Consulting Engineers on behalf of Wyeth Medica Ireland. The barrow measured approximately 12m in external diameter. The ditch was 2.4m wide and 1.6m deep. A series of cremated bone deposits was excavated at the centre of the barrow, and Bronze Age pottery sherds were recovered from one of the central cremations. The ditch fills contained later prehistoric material. Post-excavation analysis is ongoing. The barrow was found to be enclosed by a field system.
A complex of medieval ditches and gullies was excavated to the south of the Wyeth Medica Ireland biotechnology campus, adjacent to the site of Nangor Castle. A large assemblage of medieval pottery was recovered. Also in Nangor townland, a small fulacht fiadh was excavated following topsoil stripping.
