The Battle of Clontarf website was created for students and the public to provide access to historical and archaeological information and resources on one of the most emblematic battles in Irish history.

It is hoped that these sections may help enrich the readers's understanding of life in Ireland in 1014.  The site explores:

  • Social Context: daily-life in Viking-Age Ireland
  • People: the key players of Clontarf
  • Politics: the rivalries that led to the battle.
  • Dynamic interactive maps allow you to explore Viking raids and settlement development, Brian Boru’s military campaigns and what happened on Good Friday, 23 April 1014.
  • Traveling the timeline you can discover how Brian rose to power and the different challenges overcame in order to become high-king of Ireland.  
  • Remembering Clontarf: an important section of this website also explores the many different ways in which Brian and the battle have been remembered in the thousand years since it occurred.

Articles are hyperlinked to a number of medieval and modern historical sources that are freely available online as well as a number of museums and libraries that offer public access to their collections (the names of which can be found on our 'Credits' page).

This website was developed for the millennial anniversary of the battle in collaboration with medieval historians from Trinity College Dublin’s Department of History under the auspices of Professor Seán Duffy and the university’s Centre for High Performance Computing, managed by Dermot Frost.
