Farmleigh's Walled Garden is a feast for the senses. Dating back to the early 19th Century, the gardens are filled with a wide variety of unusual flowers and plants.
The garden contains a temple, designed by Lanning Roper, that is similar to those found in the famous Bagatelle Garden in Paris. A paved rose garden was laid out to the north-east of the temple, backed by a yew hedge and looking across a lawn to the small orchard. Lanning Roper suggested planting a quince, a mulberry, a catalpa, and a magnolia, to complete what he described as a 'Carolingian Quartet'.
