Robert M Chapple's Catalogue of radiocarbon determinations & dendrochronology dates is a free-to-download resource for Irish archaeology.

The resource was originally developed for the author's own research needs and is provided here 'as is' for any research project, public or private, that may benefit from it.

I am always in search of new data to include in this resource. If you possess published/unpublished radiocarbon or dendro dates from Irish sites and would like to see them disseminated to a wider audience, please feel free to contact the author at or join the Facebook Group
