Mount Stewart is one of the most inspiring and unusual gardens in the National Trust's ownership.
The National Trust took over the gardens in 1957. The last chatelaine of the house (and the last surviving child of the 7th Marquess), Lady Mairi Bury (née Vane-Tempest-Stewart, Dowager Viscountess Bury), gave the house and most of its contents to the Trust in 1977. The Trust operates the property under the name "Mount Stewart House, Garden & Temple of the Winds". Lady Mairi was the last Londonderry family member to live at Mount Stewart, and the last member of this Anglo-Irish family to live in Ireland. She died at Mount Stewart on 18 November 2009, at the age of 88. On her death her daughter Lady Rose Lauritzen, wife of the American art historian, became the live-in family member; she lives also in Venice.
In 2015, the National Trust completed an extensive restoration of the house and its contents as well as the purchase of the wider estate re-uniting it and plan to open for visitor access.
The garden reflects a rich tapestry of design and great planting artistry that was the hallmark of Edith, Lady Londonderry. The mild climate of Strangford Lough allows astonishing levels of planting experimentation. The formal areas exude a strong Mediterranean feel and resemble an Italian villa landscape; the wooded areas support a range of plants from all corners of the world, ensuring something to see whatever the season.
The Trust Wardens have requested that any squirrel sightings be reported to them
They would like to know the location and if the squirrel is red or grey. They can contacted in person on site or you can tweet @NTRangerToby or @NTmountstewart
