The project has had both academic impact and non-academic impact. Academic impact has been achieved through demonstration of the successful dating of mortars of known age with the technique. This has opened up further avenues of research and collaborations with archaeologists and has generated considerable interest in those wishing to submit mortar samples for analysis. The research and results have also resulted in a number of articles in leading archaeological journals (Journal of Archaeological Science, Archaeometry), in turn leading to continued funding for on-going projects (Royal Irish Academy Archaeology Research Grant).

Societal impact has been achieved, for example, in the work carried out in collaboration with the Derry Tower Heritage Group. This resulted in the discovering of a previously unknown Irish round tower, the last known remaining monastic medieval building in the city of Derry. This finding received considerable news and press coverage, for example, featuring on RTE News (Ireland’s state broadcaster) and the BBC News website. Plans are in place by Derry Tower Heritage Group to develop the site and monument for the benefit of locals, visitors and tourists. Work is also on-going on a project to date the round towers of Northern Ireland, in collaboration with the Historic Environment Division, Northern Ireland, and the Royal Irish Academy, Republic of Ireland. The results of this work will have significant impact when completed.
