While in France I visited Carcassonne. This amazing fortress stands on a hill that can be seen for miles around. I and my companions were puzzled while walking round the ancient ramparts at what appeared to be yellow paint daubed on the historic walls. We eventually found a notice explaining what it is all about. I thought it was fantastic. However:
“Dubbed “Concentric, eccentric”, the project is the brainchild of contemporary Swiss artist Felice Varini, famed for creating illusions of flat graphics superimposed on three dimensional spaces via an eye-deceiving technique called anamorphosis.

Varini got local art students to attach thin aluminium strips painted yellow to the the fortress in southwestern France, a popular tourist destination which was fully restored in the 19th century, after projecting the circles onto its huge stone surface at night.”
However, local people were not impressed and raised a petition to have it removed.
“One inhabitant told France Info radio: ”The people of Carcassonne were not consulted. This is ruining our lives, because we have to look at it all day.”” https://www.telegraph.co.uk/news/2018/05/11
Predictably, my fellow travellers also complained about ruining a historic building, even after learning the design was made with tape, not paint. The Tour Guide had more sense and suggested that the idea was to get people talking about it, as we were at that moment.
