Glenveagh Castle is located in the stunning Glenveagh National Park in co.Donegal. It was built between 1867 and 1873 by Captain John Adair who tried to recreate a castle retreat better than Balmoral. He was also responsible for evicting 224 tenants from his land, a job which involved 200 police officers, the local magistrate and the sub sheriff. Many of those evicted went to the work house in Letterkenny and some were helped to emigrate to Australia by the Donegal Relief Fund and were settled in Sydney. Henry Plumer McIlhenny from Philadelphia purchased the estate in 1937 and had plenty of interesting guests amongst them Greta Garbo and Marilyn Monroe. He finally left the castle and gardens to the nation in 1981 and now it is in the care of the Office of Public Works. He furnished each of the rooms with very different characters, some in the period of the castle, others from different periods. The gardens also World class containing plants from all over the world which were planted under the advice of leading landscape artists James Russell and Lanning Roper. There is an 18 stop garden tour showing some of the most beautiful parts. The gardens are especially spectacular for the rhododendrons in May and June and the walled garden in August.
