Battle Abbey is a historic site in Battle, East Sussex, marking the location of the 1066 Battle of Hastings.
William the Conqueror founded the Benedictine abbey around 1070 as penance for the battle’s bloodshed, dedicating it to the Holy Trinity, the Virgin Mary, and St. Martin of Tours; its high altar was placed where King Harold reportedly fell. Construction began under William but finished later, with the church consecrated in 1094. The abbey thrived until Henry VIII’s Dissolution of the Monasteries in 1538, after which its lands were granted to Sir Anthony Browne.
Managed by English Heritage as “1066 Battle of Hastings, Abbey and Battlefield,” the site includes extensive ruins and a visitor centre.
