Renovation Notice

The gardens will be closed from July 10, 2017, until March 15, 2018. A reduced season pass is available.


Temporary Closure of Gardens from July 2017

At Dumbarton Oaks, we are committed to preserving and maintaining our historic gardens and collections to the highest standards, while incorporating technological improvements that will ensure their good repair and longevity. We are just finishing a yearlong renovation of the museum, which will reopen in late April.

The time has now come to undertake large-scale improvements to the gardens’ water-supply network, which dates to the gardens’ original creation in the 1920s. We are therefore obliged to close the gardens to the public from July 10, 2017, to March 15, 2018. We will take this opportunity to enhance storm-water management throughout the property, in keeping with our commitment to sustainability and the environment. We invite you to enjoy the gardens before their temporary closure on July 10; you can purchase a reduced season pass here. (Admission is free until the beginning of our regular season on March 15.)

About the Gardens

In 1920, after a long and careful search, Mildred and Robert Woods Bliss found their ideal country house and garden within Washington, DC. They purchased a fifty-three-acre property, described as an old-fashioned house standing in rather neglected grounds, at the highest point of Georgetown. Within a year the Blisses hired landscape gardener Beatrix Farrand to design the gardens. Working in happy and close collaboration for almost thirty years, Mildred Bliss and Beatrix Farrand planned every garden detail, each terrace, bench, urn, and border.

Since that time, other architects working with Mildred Bliss, most notably Ruth Havey and Alden Hopkins, changed certain elements of the Farrand design. The gardens have also changed in function. In 1940, Mildred and Robert Woods Bliss gave the upper sixteen acres to Harvard University to establish a research institute for Byzantine studies, Pre-Columbian studies, and studies in the history of gardens and landscape architecture. They gave the lower, more naturalistic twenty-seven acres to the United States government to be made into a public park. An additional ten acres was sold to build the Danish Embassy.

In 1941, anticipating the inevitable changes that would accompany the gardens' different function, Farrand began to write a Plant Book, to define her design intentions and suggest appropriate maintenance practices. Her suggestions for stewardship still prove useful today, more than sixty years later.
