About the garden

Owned by
National Trust

Designed By
Thomas Mawson

A peaceful oasis on the outskirts of Cardiff, Dyffryn Gardens covers more than 22.2 hectares (55 acres). The Edwardian gardens are a restoration project on a path to excellence. With year-round seasonal highlights, the gardens feature the best woody collection in the National Trust. Discover intimate garden rooms including the Pompeiian garden, Paved Court, Reflecting Pool and Mediterranean garden. The enormous great lawn is bordered by seasonal bedding and a croquet lawn. There is also a large glasshouse, statuary collection and arboretum featuring trees from all over the world as well as the Log Stack play area, which is great for kids and adults alike. 

Designed by eminent landscape architect Thomas Mawson in 1906, the gardens are the early 20th-century vision of coal magnate John Cory and his son Reginald. Within the gardens, Dyffryn House, a grand Victorian mansion, overlooks the key aspects of the garden but is closed to the public.
