On the ground floor was a hothouse used for growing, among other things, pineapples.Smoke from the heating system was expelled from chimneys disguised as Grecian urns. Pineapples were 'discovered' by Christopher Columbus on the Caribbean island of Guadeloupe in 1493. They became a rare delicacy in Europe and were a powerful symbol of wealth, hospitality and agricultural innovation.
In 1970 the Dunmore Estate was broken up and sold in separate lots. The Pineapple was bought by the Countess of Perth who late sold it to the National Trust for Scotland in 1974. The Trust in turn leased the folly to the Landmark trust who let the two gardener's bothies(cottages) as holiday accomodation.
