Kelburn Castle is prominently located on the west coast of Scotland, 35 miles west of Glasgow, overlooking the sea. Kelburn is supposedly the oldest castle in Scotland to have been continuously inhabited by the same family, and probably built before 1200 AD. In 1977 the tenth Earl of Glasgow and his wife, opened most of Kelburn’s grounds and gardens to the public and introduced new attractions.
It seems an earlier attempt to restore the castle walls used a cement, or stucco if you will, that is actually damaging the original stone walls, and must be removed/replaced in a couple of years. So the Earl and his Mrs, got permission from Historic Scotland to bring four famous graffiti artists from Brazil, and paint the place.
This is how it looked before the project started:
