Belvoir Castle, the Duke of Rutland's pad in Leicestershire, is the setting for an annual teddy bears' picnic in its stately grounds.
But visitors to its website the other day would have been bemused to find images of the castle replaced by the Algerian flag and a message in Arabic denouncing Israel.
The geographically challenged Algerians who perpetrated the hack had confused this slice of aristocratic England with Belvoir Fortress, a former Crusader garrison 2,000 miles away in Israel.
