About the garden

Owned by

The garden at Mount Stewart is unique and of rare quality, being one of the few late compartmentalised Arts and Crafts-like gardens. It is a deeply personal garden, the creation of Edith, Lady Londonderry in the early 20th century, building on a pre-existing historic 18th and 19th-century landscape.

A strong artistic theme is combined with an unrivalled plant collection, which is protected and augmented via the nursery and propagation operation situated in the old walled garden. 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 beautiful blooms whatever the season. Considered to be one of the most outstanding gardens in the world, Mount Stewart is one of the most visited National Trust mansion house properties in Northern Ireland.

Please note: This garden is partially accessible.
