Celebrated Mount Stewart garden wins European Garden Award for ‘exemplary’ climate mitigation measures - National Trust

The National Trust’s Mount Stewart in County Down has received a first prize for Climate Mitigation Measures in Parks or Gardens in the European Garden Award.

The prestigious award is given by the European Garden Heritage Network, which represents some 210 parks and gardens across 21 countries, and the Germany-based Schloss Dyck Foundation, a centre for Garden Design and Landscape Culture. It is seen as a ‘seal of quality’ for outstanding achievement in contemporary garden design, the management and development of historic gardens and climate adaptation measures.

The celebrated garden was one of three to be awarded first prize in the category, which was introduced in 2022.

Mount Stewart is a rare late Arts and Crafts garden, and its deeply personal, artistic ‘rooms’ – filled with an unrivalled plant collection – were created by Edith, Lady Londonderry, in the early 20th century. It is considered one of the most outstanding gardens in the world.

But warmer summers, wetter winters and rising sea levels are already altering the gardens which are set on the shore of Strangford Lough, the largest sea inlet in the British Isles, in Northern Ireland. Modelling suggests it is very likely that the most famous area, the Formal Gardens, will be slowly consumed by both salt and rainwater sometime in the next 100 years.

The team here is among the first in the National Trust to assess the risks posed by climate change and to make detailed plans for the future. This includes working with partners to understand localised climate impacts, maintaining the historic ‘sea plantation’ which shelters the area near the house, and introducing plants that are more resilient to windy and salty conditions. This will be a mix of native plants as well as adaptive, fast-growing plant species from Chile, South Africa, New Zealand, and the eastern seaboard of the USA.
