National Monuments Service - Holy Wells in the Republic of Ireland

This dataset displays locational information for all 3,023 Holy Wells in the Republic of Ireland that has been recorded by the National Monuments Service. The dataset contains information on certain holy wells the precise location of which has not been identified and as a result have been assigned the National Grid Reference of 0/0. It is hoped with the publication of this dataset that some of these ‘lost holy wells’ may be located by public information which can be sent by email to The dataset provides the Sites and Monuments Record (SMR) Number for each holy well along with a link to a more comprehensive online entry available on the National Monuments Service, Historic Environment Viewer, accessible at This information is correct at the time of publication. It may be amended or altered by the addition or removal of Holy Wells based on information submitted to the National Monuments Service. This dataset is based on information exported from the national database on the 01/01/2021.

Provenance information It is important to note that this mapping uses the Irish Transverse Mercator (ITM) co-ordinate system. In order to facilitate users during the transition from Irish Grid (IG) to ITM, downloads will include both sets of co-ordinates. The existing point centroids for the records were digitised relative to the OSI 6-inch mapping and the move from this older IG-referenced series to the larger-scale ITM mapping will necessitate revisions.
