Londonderry’s historic city walls are the most vandalised monument in Northern Ireland, according to new figures.
A total of 193 incidents have been recorded by the Department for Communities on the walls between April 2021 and April 2025.
That equates to 65% of all incidents recorded at historic monuments in Northern Ireland over during the same time.
The city’s walls date back to the 1600s. They are Northern Ireland’s largest state monument and one of the city’s most popular visitor attractions.
John Anderson from the Ulster Architectural Heritage Society said the accessibility of the walls made them “much more liable to attacks of this nature”.
“This vandalism is the bottom of the scale of a very large problem that goes way beyond monuments,” Mr Anderson said.
“Whether it’s graffiti on Derry’s walls or whether it’s arson on a listed building, these are criminal acts.
“Appreciation and value of the national asset that is built heritage, in all its forms, is in basically the cultural approach of any country, and that cultural approach needs to be led by example by the leaders of that country.
“Unfortunately the leadership over the decades in Northern Ireland hasn’t been there, the sector is chronically underfunded, worse now than ever it was, and coming down to the graffiti level – presumably that is mostly youngsters – it’s an easy target,” Mr Anderson said.
Geraldine Henderson from Glasgow and Patricia Mundy from Leeds are among the thousands of tourists visiting Derry this week.
Patricia told Radio Foyle’s North West Today programme it was both “disgraceful and appalling” that the walls should be subject to repeated vandalism.
“It is absolutely disgraceful after all that you have been through here,” she said.
“First of all it’s a pride thing and because of the heritage of Derry. It’s a place like people like to come.”
Geraldine said looking after the walls was looking after the city’s heritage.
“It’s important to keep them for the history…. and I think we should all respect each other’s history.”
Janice McNeilly told Radio Foyle there is a vibrancy to the walls as well as a sense of history.
“People from all over the world appreciate them, we sort of get used to them, they are in the background,” she said, adding it “would be a shame to see anything happen to them.”

The figures in relation to vandalism were revealed in response to an assembly question from SDLP MLA Justin McNulty.
Stormont’s Department for Communities has been asked for comment.
