Founded in the 12th century, the abbey was the supply base for the Scottish army, where vital provisions were stored.
On the night of 23 June, this store was plundered by the Earl of Atholl, a Scottish earl with wavering loyalty to Bruce. He and his men killed the guards, seized the food and disappeared into the night. This act of treachery was motivated by a personal grudge: Atholl sought revenge on Edward Bruce, who had cruelly abandoned the earl’s sister, Isabella, when she became pregnant with his son.
In November Bruce called a parliament at the Abbey at which those Scottish lords previously opposed to him were given the opportunity to come over to his side.
The ruins of the abbey can still be visited today and include an attractive bell tower. Other highlights include the tomb of James III and Queen Margaret and a fine display of medieval grave slabs.
