Overview
Mount Stewart sits on the tranquil east shore of Strangford Lough, just 24 km south‑east of Belfast. Owned by the National Trust, the estate comprises a neoclassical 19th‑century house, more than 70 acres of formally designed gardens, a picturesque lake walk and the iconic Temple of the Winds – an octagonal classical folly that offers sweeping views across the lough. The house and gardens are open year‑round, and the site is celebrated as one of the world’s top ten gardens, thanks to the bold planting schemes of Edith, Lady Londonderry, and the mild, humid climate that allows subtropical specimens to thrive.
History
The original property, then called Mount Pleasant, was bought in 1744 by Alexander Stewart, a Presbyterian linen merchant. Over the next two centuries the Stewart family – later the Vane‑Tempest‑Stewarts, Marquesses of Londonderry – transformed the modest house into a political hub. Notable residents include Viscount Castlereagh, Britain’s Foreign Secretary at the Congress of Vienna, and the 7th Marquess, a former Air Minister who entertained the German ambassador in the 1930s.
In the early 19th century the 3rd Marquess rebuilt the façade in a grand neoclassical style, adding the central Ionic portico and two roof domes that still illuminate the main hall. After a period of neglect in the early 20th century, Lady Edith (Lady Londonderry) inherited the estate in 1915. She re‑imagined the gardens, creating the Italian, Spanish, Shamrock, Mairi and Sunken gardens, and introduced exotic plantings that flourish under the North Atlantic Drift.
The last family occupant, Lady Mairi Bury, gifted the house and its contents to the National Trust in 1977. A major three‑year restoration, completed in 2015, returned the interiors to their 1950s appearance and refreshed the gardens for a new generation of visitors.
What to See & Do
| Feature | Highlights |

| The House | The dramatic central hall lit by a roof dome, the yellow dining room (once host to Winston Churchill), the black‑and‑white stone hall with French Imperial Guard armour, and a portrait collection that includes a painting of Napoleon III. |
| Temple of the Winds | Designed by James ‘Athenian’ Stuart (1782‑83), the octagonal folly mirrors the ancient Tower of the Winds in Athens and provides panoramic views of Strangford Lough. |
| Italian Garden | Geometric parterres of reds, yellows and oranges, classical statuary, and a herm‑adorned southern wall that references Lady Londonderry’s self‑styled “Circe”. |
| Spanish Garden | Cypress arcades, a blue‑green tile‑lined water parterre, and a salmon‑pink limestone well head rescued from the Chelsea Flower Show of 1926. |
| Shamrock Garden | Topiary depicting Irish myth, a children’s story‑inspired hedge, and an evolving Formorian statue that nods to local folklore. |
| Mairi Garden | Blue‑and‑white flower beds echoing the Stewart family colours, with a bronze statue commemorating the birth of Lady Mairi. |
| Lake Walk | A 0.6 mi circular, mostly level trail around a seven‑acre lake, passing the private burial ground Tír na nÓg, historic jetty, and a collection of rhododendrons. The walk is wheelchair‑friendly, though some sections are gravelly. |
| Fernery & Walled Rose Garden | Recent restoration work has revived rare ferns and a historic rose garden, offering quieter, woodland‑style experiences. |

Beyond the formal gardens, the demesne includes 12 km of walking trails that wind through woodland, farmland and the rolling drumlin landscape of the Ards Peninsula. Wildlife enthusiasts can spot red squirrels, seals from the Lough Lookout, and a variety of breeding seabirds.
