A COUNTY BY COUNTY REFERENCE LIST FOR VIKING ACTIVITIES IN
IRELAND AS DESCRIBED IN THE ANNALS


The following list is a preliminary attempt by Lenore Fischer to put together a geographical reference for events involving Vikings that happened in specific areas.
Given the resources for onomastic research in Ireland, there are many place names which have still to be identified with a degree of certainty so this is merely intended as a basic
introduction. For further reading on these issues, see C. Etchingham, Viking raids on Irish church settlements in the ninth century : a reconsideration of the annals (Maynoo1996) – especially the Appendix and Clare Downham, “The Vikings in Southern Uí Néill to 1014”, Peritia 17-18 (2003-2004) 233-55.
The following is essentially a list organised by county and its focus are Scandinavian activities outside the main urban enclaves. The evidence for the Viking
settlements of Dublin, Limerick, Waterford and Wexford has been omitted as making the attached file too large to be of use.
As Ireland’s larger lakes border on several counties, it was found more convenient to place them separately at the end.
