The work of four Brazilian graffiti artists on Kelburn Castle has already set it apart and now it has secured £1m of funding to support the expansion of its luxury camping site.

The 13th century castle and 3,500 acre estate near Fairlie in North Ayrshire has been owned by the Boyle family since 1140. The present owner, Patrick Boyle, the 10th Earl of Glasgow, opened up the castle along with its grounds and gardens to the public in 1977.

Later he brought together four of the world's leading graffiti artists from Brazil to work alongside Scottish talent, to create a burst of colour on the walls and turrets of the south side of the castle.

A number of new attractions were introduced over the years and, following a 400 per cent uptake in the estate’s glamping (luxury camping) experience, the Boyle family approached Barclays Bank for support in restructuring borrowings and secure investment capital.

David Boyle, son of the 10th Earl of Glasgow and Commercial Manager of Kelburn Castle and Estate, said of the £1m backing: “This deal marks the first time our family has banked with Barclays, and I have to say that the experience and service has been unrivalled. We needed a banking partner that would take the time to understand the heritage of our business but also recognise our ambition for growth. "
