A medieval gatehouse at Battle Abbey is the only place that offers panoramic views of the landscape where the Battle of Hastings was fought in 1066. And 950 years on from the clash that ended the Anglo-Saxon phase of English history, it's being opened for the first time.
To mark the anniversary, members of the public will be able to walk up the 66 steps to the top of the abbey to take in the scene where William the Conqueror marked his victory over the English.
Visitors to the site in Battle, East Sussex, will also see the new location of the memorial stone that marks the place where England's King Harold is said to have died.
And for the first time they can access, through the original 13th-century doorway, the large dormitory where the medieval Benedictine monks slept, until England's monasteries were destroyed under Henry VIII in the 16th century.
From the top of the gatehouse, people will have a 360-degree view of the Sussex countryside, including the hills where the two sides made their stands before battle, William of Normandy on Telham Hill and Harold and his army on Caldbec Hill.
