HOW about this story in the Daily Mail explaining how experts went to precise lengths to achieve historical accuracy:-

One of the most important spots in British history has just been moved - by seven yards.

950 years after King Harold was killed at the Battle of Hastings, the exact place where he fell has finally been located by English Heritage historians in the town of Battle, East Sussex.

And now the stone memorial marking the spot has been shifted seven yards to the east, to mark the spot where William the Conqueror’s army killed him with an arrow through his eye.

Early historians believed that the high altar of the abbey church was built on the exact spot where Harold fell on October 14, 1066 but after Henry VIII destroyed the church in 1538, the site of that high altar was lost - until now.

An English Heritage spokesman said: “What was previously marked as the spot was close but we now know it stood slightly further east.”
