The town now standing on the site of the Battle of Hastings is Battle, in East Sussex.
Despite its famous name, the battle was not fought in the modern town of Hastings. William of Normandy’s army advanced from Hastings, where William had established a castle and base, to meet Harold Godwinson’s English army several miles inland. Harold took up a defensive position on Senlac Hill, close to the settlement that later became known as Battle.
After the Norman victory, William founded Battle Abbey on the battlefield. Tradition holds that the high altar was built where Harold was killed, although the precise location remains debated. The abbey became the centre of a new community, and the settlement’s name eventually reflected the historic event. The surviving abbey ruins and battlefield are now managed as a major heritage site.
Hastings, Pevensey and Rye are all nearby places associated with the campaign, which makes them plausible wrong answers. Pevensey was where William landed, Hastings was his military base, and Rye was another important coastal settlement; Battle is the town directly occupying the battlefield area.
