Dunmore Pineapple - The Walled Garden at Dunmore Park

The Walled Garden At Dunmore Park

Dunmore Park, the ancestral home of the Earls of Dunmore, includes a large country mansion, "Dunmore House", and grounds which contain, among other things, two large walled gardens. Walled gardens were a necessity for any great house in a northern climate in the eighteenth and nineteenth century, as a high wall of stone or brick helped to shelter the garden from wind and frost, and could create a microclimate in which the ambient temperature could be raised several degrees above that of the surrounding landscape. This allowed the cultivation of fruits and vegetables, and also of ornamental plants, which could not otherwise survive that far north.

The larger of the two gardens covers about six acres, located on a gentle south-facing slope. South-facing slopes are the ideal spot for walled gardens and for the cultivation of frost-sensitive plants. Along the north edge of the garden, the slope had probably originally been more steep. To allow both the upper and lower parts of the garden to be flat and level at different heights, it was necessary to bank up the earth on the higher northern side (away from the main house), behind a retaining wall about 16 feet high, and a solid 3 feet, 3 inches thick, which runs the entire length of the north side of the garden.

Walled gardens sometimes included one hollow, or double, wall which contained furnaces, openings along the side facing the garden to allow heat to escape into the garden, and chimneys or flues to draw the smoke upwards. This particularly benefited fruit trees or grape vines that could, if grown within a few feet of a heated, south-facing wall, be grown even further north than the microclimate created by a walled garden would normally allow.
