Kellie Castle in Fife dates from as early as the 14th century and has magnificent plaster ceilings, painted panelling and fine furniture designed by Sir Robert Lorimer. It also contains a long-concealed mural by the celebrated Arts & Crafts pioneer, Phoebe Anna Traquair. The grounds and garden could easily be a day out in themselves, with acres of woodland walks, a bird hide and an abundance of nature. www.nts.org.uk/Property/Kellie-Castle-and-Garden
