In short, this is essentially Cash in the Attic but on a slightly larger scale more befitting primetime viewing. Antiques Roadshow regular John Foster helps to prop up struggling historic houses by uncovering valuable heirlooms that the families can sell.

Borris House in Co Carlow is the ancestral home of the MacMorrough Kavanaghs, High Kings of Leinster. The stunning, 16th Century home, on 650 acres, is the only Irish property to feature on this new series, wouldn't you know.
