Glenveagh Gardens

Walled garden



The site occupied by the Castle and Gardens was wild mountain moorland. In 1869 the first part of the Castle was constructed. However it was not until the mid 1880's that the Gardens were started. The two major elements of the Garden, the Pleasure Gardens and the Walled Garden were constructed in the late 1880's. The original Victorian Garden layout remains intact. It was for Mrs. Cornelia Adair that the gardens were constructed. Mrs. Adair employed a Kew trained gardener to lay out the gardens. Some of the planting in the Pleasure Grounds such as the purple maples and the Scots pine trees were planted at this time.

In 1929 Lucy and Arthur Kingsley-Porter became the new owners. They were also keen gardeners and Mrs Porter brought the dahlia known as Matt Armour to Glenveagh.

The last private owner, Henry P McIlhenny began to develop the gardens in the late 1940's with the assistance of Jim Russell of Sunningdale Nurseries and Lanning Roper, the well-known garden consultant. From the late 1950's through to the early 1980's the design and layout of the garden was developed to include the Gothic Orangery, the Italian Terrace, the Tuscan Garden and the development of the plant collection.

Glenveagh is well known today for its rich collection of trees and shrubs specialising in southern hemisphere species and a diverse Rhododendron collection. Displays of Rhododendrons are at their best from late March to the end of May.

Displays of colour in the Walled Garden are at their best through the summer months.

Access to the Gardens is from dawn to dusk all year round. Admission to the Park, including the Gardens is free.
