Garinish Island or Ilnacullin is an island of 15 hectares in Glengarriff Harbour and it is an island garden of rare beauty known to horticulturists and lovers of trees and shrubs all around the world.

The gardens of Ilnacullin owe their existence to the creative partnership, some 70 years ago, of Annan Bryce, then owner of the island and Harold Peto, architect and garden designer. Once a coniferous shelter belts had been established, it was possible to implement Peto’s designs to create the distinctive gardens of Ilnacullin. After the death of Annan Bryce in 1923, the development of the gardens was continued by his widow, Violet. In 1932, their son, Rowland Bryce, took over this work, continuing to add interesting plants from many parts of the world. He was ably assisted by Murdo Mackenzie, an outstanding Scottish gardener. On the death of Rowland Bryce in 1953, the island was bequeathed to the Irish people and entrusted to the care of the Commissioners of Public Works. Murdo Mackenzie remained in charge of the garden when it passed into public ownership until his retirement in 1971. Today, management of the island is in the hands of the Office of Public Works.

The alternative name Ilnacullin or Illaunacullin (Island of Holly) also has a long history in the locality, and appears on at least one early map; it may in fact be the older name for the island. As there is another island garden called Garnish not far away in County Kerry, there is much to be said for using the distinctive name Ilnacullin for the island garden at Glengarriff, County Cork, and this has been the practice of the Office of Public Works for some years now.


Annan and Violet Bryce were convinced that with its sheltered situation and the warming influence of the Gulf Stream, a wide range of oriental and southern hemisphere plants could flourish in the almost subtropical climate of Glengarriff. Keenly interested in horticulture and architecture, the Bryces planned to build a mansion and lay out an extensive garden on the island. They commissioned the eminent English architect, Harold Peto, to design these. Plans for a mansion were prepared incorporating the Martello Tower, but it was never built. Instead an extensive cottage became the home of the Bryce family. Among their guests were the writers George Bernard Shaw, who stayed on the island in 1923 while writing his play, Saint Joan, and the poet, Æ George Russell.

Harold Ainsworth Peto (1854 – 1933) was an advocate of the Italian style of architecture and garden design although the wild Robinsonian style of gardening dominated his epoch. However, Peto believed that more formal styles could co-exist with the Robinsonian style and ought not to be neglected. The Italian Garden is, perhaps, the outstanding feature of Garinish. Here, Peto’s genius, combined with Annan Bryce’s ideas and resources, resulted in the creation of a formal architectural garden which blends well with its natural setting. An Italian tea-house or “Casita” of Bath stone with colonnades, a formal pool, an Italian pavilion with columns of “Rosso Antico” of a beautiful red colour, a Grecian Temple, marble slabs from Carrara, the Island of Scyros and Connemara are just some of the architectural features.
Ilnacullin is renowned for its richness of plant form and colour, changing continuously with the seasons.

The vivid colours of Rhododendrons and Azaleas reach their peak during May and June, whilst the hundreds of cultivars of climbing plants, herbaceous perennials and choice shrubs dominate the midsummer period from June to August. Autumn colour, particularly on the magnificent heather bank, is rich during the usually mild autumn months of September and October.
