Historic Environment Scotland (HES) is appealing to the public for information after a "very serious incident of heritage crime" took place at a historic abbey in Ayrshire.

The damage was done to the 13th century pier of Kilwinning Abbey, which supports the arched entrance into what used to be the abbey’s south-west tower.

One of the lower courses of the pier has been completely destroyed, with the stone still lying on the scene of the crime, HES said. 

HES is now working closely with Police Scotland to investigate the incident. To avoid any further damage to the pier, a replacement stone will be cut using templates from the neighbouring stones and installed into the void.

Gillian Gardner, Physical Security Senior Manager at HES, said: “This is the worst case of heritage crime I have seen in a long time. It is heart-breaking to see historic fabric destroyed in this manner.

“As highlighted in our recent campaign with CrimeStoppers and Police Scotland, heritage crime is a serious matter which damages our historic sites and robs us of our history.

"Reckless acts such as this one carry the risk of serious injury to both the perpetrator and anyone else on-site. Not only is it dangerous, but this kind of vandalism has a knock-on effect on all of our sites, as our conservation specialists are pulled away from their core conservation work on other monuments to tend to these incidents.

“We urge anyone with information regarding this incident that could help investigations to get in touch with Police Scotland on 101; or Crimestoppers anonymously on 0800 555 111 or crimestoppers-uk.org.”

Kilwinning Abbey was founded in the late 1100s. It has close ties to Kelso Abbey, one of Scotland’s great Borders abbeys, which provided it with colonising monks. 

The abbey was ‘cast down’ following the Protestant Reformation of 1560, though its south transept still stands nearly to its full height today. 

Back in April 2022, vandals caused “irreversible damage” at the abbey after a stolen wheelie bin was set alight within the ruins.
