An archaeological study of the Battle of the Boyne at Oldbridge, Co. Meath.

This paper outlines the results of a pilot archaeological study carried out on the Oldbridge Estate, Co. Meath, Ireland, in advance of its development for the presentation of the events of the Battle of the Boyne which was fought by the forces of King William III and James II on 1st July 1690. Archival research including the examination of museum collections, cartographic sources, contemporary artistic depictions of the battle and recent aerial photographic coverages was followed up by the use of a range of archaeological techniques including systematic surface collection survey, soil phosphate analysis, magnetic gradiometry, metal detecting and limited test excavation. Additionally, marine geophysics equipment was used to profile the character of the River Boyne, especially in the area of the main crossings. The study revealed important new evidence including the establishment of the location of Oldbridge village, a pivotal feature in the conduct of the battle, the confirmation of the location of the first engagement on the day of the battle and the first systematically recovered artefacts from the battlefield
