During the 1850s, the Herberts undertook extensive garden works in preparation for Queen Victoria`s visit in 1861. Later, the Bourn Vincent family continued this gardening tradition. They purchased the estate from Lord and Lady Ardilaun early in the twentieth century. It was at this time that the Sunken Garden, Rock Garden and the Stream Garden were developed. Many exotic trees and shrubs flourish in the mild climate and sheltered location of the Muckross gardens. Attractive features include a fine collection of rhododendrons and azaleas, an outstanding rock garden on a natural rock outcrop and beautiful tree-fringed lawns.
