About
Mount Stewart on the shores of Strangford Lough in County Down is one of Northern Ireland's greatest historic properties and one of the National Trust's most celebrated garden estates in Ireland. The house, its extraordinary gardens, and its remarkable political associations combine to create one of the most compelling historic sites in the British Isles.
The house is principally associated with the Vane-Tempest-Stewart family, Marquesses of Londonderry, who have owned the estate since the eighteenth century. The main house was built in the 1820s and 1830s to designs by William Vitruvius Morrison, incorporating and greatly expanding an earlier wing. The interiors retain outstanding collections of furniture, portraits, and decorative arts, many associated with one of the family's most famous members: Robert Stewart, Viscount Castlereagh (1769-1822), who served as British Foreign Secretary during the Napoleonic Wars and represented Britain at the Congress of Vienna in 1815. Castlereagh is among the most consequential — and controversial — British statesmen of the nineteenth century, and the house holds significant objects and portraits associated with his career.
The gardens are the creation of Edith, Lady Londonderry — wife of the 7th Marquess — who began transforming the grounds in the 1920s. Working with the exceptionally mild microclimate of the Ards Peninsula, which allows plants from the Mediterranean, Australia, New Zealand, and South America to flourish outdoors, Lady Londonderry created a series of garden rooms of extraordinary beauty and botanical ambition. The Italian Garden, the Spanish Garden, the Mairi Garden (made for her daughter), the Shamrock Garden (with its extraordinary Red Hand of Ulster topiary), and the walled Lady Mairi's Garden each have their own distinct character and atmosphere.
The Temple of the Winds (1785) is a neoclassical garden folly by James 'Athenian' Stuart perched on a promontory overlooking Strangford Lough — one of the finest eighteenth-century garden buildings in Ireland. The lakeside setting, the walled garden, and the magnificent mature trees and plantings of the wider pleasure grounds complete a garden estate of exceptional richness.
Mount Stewart passed to the National Trust in 1977 and has been extensively conserved and interpreted in the decades since, making it one of the Trust's most visited and admired properties in Ireland.

Highlights
The Gardens: Lady Londonderry's Masterwork
The gardens at Mount Stewart are among the finest in the British Isles and represent the life's work of Edith, Lady Londonderry, who began creating them in the 1920s. Working with the exceptionally mild microclimate of the Ards Peninsula — warmed by the Gulf Stream and rarely touched by frost — she planted specimens from Australia, New Zealand, South America, and the Mediterranean that would struggle to survive almost anywhere else in Ireland or Britain.
A series of distinctive garden rooms — the Italian Garden, the Sunken Garden, the Spanish Garden, the Dodo Terrace, and the Shamrock Garden — each have their own character and botanical character, creating a garden of extraordinary diversity and beauty.
Viscount Castlereagh and the Congress of Vienna
Robert Stewart, Viscount Castlereagh (1769-1822) is one of the most significant — and most debated — statesmen in British and Irish history. As Foreign Secretary and Leader of the House of Commons during the Napoleonic Wars, he represented Britain at the Congress of Vienna (1815), where the post-war order in Europe was settled.
The Mount Stewart collections include portraits, personal objects, and documents associated with Castlereagh and his career, providing a rare opportunity to engage with the material world of one of the key architects of nineteenth-century European diplomacy.
The Temple of the Winds
Perched on a promontory above Strangford Lough, the Temple of the Winds is a jewel of eighteenth-century neoclassical architecture and one of the finest garden buildings in Ireland. Designed by James 'Athenian' Stuart — a pioneering figure in the Greek Revival movement — and built in 1785, the temple is modelled on the Tower of the Winds in Athens.
The interior features an exquisite inlaid floor and decorated ceiling.
The views from the temple across Strangford Lough are breathtaking and alone justify the walk to reach it.
The House Interiors and Collections
The main house at Mount Stewart, built to designs by William Vitruvius Morrison in the 1820s and 1830s, contains outstanding collections of furniture, portraits, and decorative arts accumulated by the Vane-Tempest-Stewart family across three centuries. The principal rooms — including the Octagon Hall, the drawing rooms, the dining room, and the library — display the tastes and collections of successive generations of the Londonderry family.
Particularly notable are the family portraits, which include works by major British artists of the eighteenth and nineteenth centuries.
