The September 11 Memorial Garden, on the east side of Grosvenor Square in Mayfair, commemorates the 67 Britons who died in the terrorist attacks on the United States on 11 September 2001. It was opened by HRH The Princess Royal on 11 September 2003, the second anniversary of the attacks.
The oval garden was designed by Land Use Consultants, with a timber pavilion and pergola by Carden and Godfrey Architects. At its centre is a stone plaque carved by the letter-cutter Richard Kindersley, beneath which was placed a small piece of rubble recovered from Ground Zero in New York.
Its most quietly remarkable feature is the planting, which was chosen in consultation with the families of those who died: a mix of North American and British species selected to be at their best in September, so that the garden comes into flower each year around the anniversary. It is the only memorial in the UK designed specifically in consultation with the bereaved families.
The garden sits within Grosvenor Square, long nicknamed “Little America”, alongside the Roosevelt Memorial and the Eagle Squadrons Memorial, and was retained in the square’s 2026 redesign.
Free to visit and open to the public.
