At the instigation of a French ambassador to the United States, Jean Jules Jusserand, L'Enfant's adopted nation then recognized his contributions. In 1909, L'Enfant's remains were exhumed from their burial site at Green Hill and placed in a metal-lined casket. After lying in state at the Capitol rotunda, L'Enfant was re-interred in front of Arlington House on a slope in Arlington National Cemetery in Virginia. His re-burial site overlooks the Potomac River and the portion of Washington, D.C., that he had originally designed.
