Situated in Georgetown, Dumbarton Oaks is a historic estate that was part of the 1702 Rock of Dumbarton land grant from Queen Anne. It was the Washington, D.C. residence of Senator and later Vice President John C. Calhoun from 1822 until 1829. Edward Linthicum named the greatly enlarged residence The Oaks in 1846. When the Bliss family acquired the property in 1920, it was called Dumbarton Oaks in honor of its two historic names. They also renovated the residence into the current Colonial Revival architectural style. In addition to the landscaped gardens, the museum features a collection of Byzantine and pre-Columbian art.
