In 2007 experts told the owners of Kelburn Castle in Scotland that its concrete facing would eventually need to be replaced to avoid further damage to the stonework. At the suggestion of his children, Lord Glasgow invited four Brazilian graffiti artists to paint the walls. The artists were Otavio and Gustavo Pandolfo or 'Os Gemeos' meaning, ‘Twins’, in Portuguese, Nina Pandolfo and Never.
Historic Scotland agreed to the project, on the basis that the graffiti would be removed when the castle was re-harled. The project was featured on the BBC television programme The Culture Show. Also in 2007, Kelburn featured in another BBC programme, Crisis at the Castle which documented the financial problems of running the castle.
