Arbroath Abbey
Arbroath Abbey was an abbey in Scotland to which Macbeth took the Stone of Destiny following its theft from Westminster Abbey in 1950.
History
There, Macbeth attempted to repair the damage that the Stone had undergone during the 1950 theft, completing it by April 11, 1951. The Stone then addressed him, healing itself and telling him how unnecessary his actions were and revealing its true nature to him.
Real-world History
Arbroath Abbey was the site of an assembly of Scottish leaders on April 6, 1320, who sent a petition to the Pope, the Declaration of Abroath. The Declaration stated their goal of winning and securing their independence from England, whose then-king, Edward II (son of Edward I), had been trying to conquer them, as his father had done.
