Dumbarton Oaks is a historic estate in the Georgetown neighborhood of Washington, D.C. It was the residence and garden of Robert Woods Bliss (1875–1962) and his wife Mildred Barnes Bliss (1879–1969). The Dumbarton Oaks Research Library and Collection was founded here by the Bliss couple, who gave the property to Harvard University in 1940. The research institute that has emerged from this bequest is dedicated to supporting scholarship in the fields of Byzantine, Pre-Columbian, and garden design and landscape architecture studies, especially through its research fellowships, meetings, exhibitions, and publications. Dumbarton Oaks also opens its garden and museum collections to the public, and hosts public lectures and a concert series. -Wikipedia Approximately nine hundred roses grow within the Rose Garden in a scheme that is dictated by color, from pinks, reds, and whites in the southern portion to oranges and yellows in the northern portion. This terrace is the largest in the series descending east from the Orangery to Lovers’ Lane Pool, and it was the Blisses’ favorite part of the garden. Their ashes are interred in the crypt beneath a lead canopy set into the west wall.-https://www.doaks.org/
