In 1902, the DAR commissioned New York architect Edward Pearse Casey to design an appropriate headquarters building and assembly hall in the Nation's Capital at 1776 D Street, NW. The Georgian Revival building of Vermont marble with monumental Ionic porticos was built between 1904-10. The meeting place for DAR conferences, it was the site of the Washington Arms Limitation Conference in 1921-22, one of the most significant international attempts to reduce global tension through disarmament and mutual pledges of arbitration.
