Police are hunting vandals after one of the oldest tourist attractions in Angus was damaged.
Staff at Arbroath Abbey were left picking up the pieces after one of its main windows was smashed.
The double-glazed window was part of the Abbot House visitor centre, overlooking an enclosed courtyard and featuring the seals from the Declaration of Arbroath.
The incident happened between 5.30pm on Tuesday and 8.30am on Wendesday.
A spokesperson for Historic Scotland said: “Our experts have assessed the damage and repairs will be carried out as soon as possible.
“We expect the cost of these repairs will be in the region of £1,000.”
The visitor attraction hosted its first wedding as an official venue last month after a two-year hiatus, and is best known for the 1320 document that formally confirmed the nobility’s support of Scottish independence from English rule.
The document was written after Robert the Bruce’s victory over the English at Bannockburn in 1314.
Arbroath Abbey was founded in 1178 by King William I “the Lion” as a memorial to his childhood friend, Thomas Becket, Archbishop of Canterbury, who was killed in 1170.
It was originally built for the grey-clad monks of the order of Tiron, and King William’s body is buried before the high altar.
The centre provides extensive displays and allows interpretation of the abbey remains and explains the Declaration’s significance.
Unfortunately, the abbey has come in for attention of the wrong sort before, after its visitor centre suffered £5,000 worth of damage last year.
Three windows were smashed on February 28 and the vandalism was condemned at the time as “mindless”.
Police Scotland appeals to anyone who was in the area and who saw or heard anything suspicious to call 101, or speak to any officer.
