ケンジントン・ガーデンズ
Among the successful campaigns by the society since the 1950s are the preservation of Leighton House, the saving of the remaining east wing of the severely bomb-damaged Holland House, and a revision of the originally proposed Princess Diana memorial garden in Kensington Gardens after the death of Diana, Princess of Wales in 1997. The proposal would have drastically changed large parts of the gardens. Instead, the compromise solution became the Diana, Princess of Wales Memorial Playground in Kensington Gardens, and the Diana, Princess of Wales Memorial Walk through Kensington Gardens, Hyde Park, Green Park and St. James's Park.
