Comedian Alan Carr has almost achieved national treasure status since winning Celebrity Traitors last year - but it's his recent purchase of a Scottish castle that he has described as his most exciting project "for ages".

It was announced earlier this year that the Chatty Man star had bought Ayton Castle in the Scottish Borders, which was on the market for offers over £3.25m, and it was rumoured he was planning to turn it into a spa and a hotel.

However in a recent podcast he rubbished the suggestion and insisted: "It is my home and I'm selling up and moving up there. It is a lovely community, really small and I want it to be magical up there."

But just how easy is it to buy your own castle north of the border? Are there many of them on the market, and do you need the bank balance of a celebrity millionaire?

Dorothy Newlands of Lauriston chairs the Scottish Castles Association which was set up to promote their conservation and restoration.
