Adjacent to Montrose Park is Dumbarton Park, a wilderness area of 27 acres that was established by Mr. and Mrs. Robert Woods Bliss who purchased Dumbarton Oaks House in 1920. Mr. and Mrs. Bliss hired Beatrix Ferrand to create the masterful 10 acre formal gardens around the house. The Blisses gave a majority of Dumbarton Oaks to Harvard University in 1940.
