The auction will take place at Ayton Castle on Sunday 5 July – with viewing on the Friday and the Saturday beforehand.
Tickets are required for both the viewing and the auction itself.
Jim Railton, of the auctioneers Railtons, explained: “Basically it’s the residual contents of Ayton Castle.
“Alan Carr, as we know, has bought the castle and he’s bought a certain amount of the furnishings.
“But the residual items that he doesn’t want – and that the last owners of the castle don’t want to take to their new house – we’re selling.”
