The Sulgrave Club is a private women's club located at 1801 Massachusetts Avenue NW on the east side of Dupont Circle in Washington, D.C. The clubhouse is the former Beaux-Arts mansion on Embassy Row built for Herbert and Martha Blow Wadsworth and designed by noted architect George Cary. During World War I the Wadsworth House was used as the local headquarters for the American Red Cross.
In 1932 a group of local women led by Mabel Thorp Boardman established the Sulgrave Club and purchased the mansion. They chose architect Frederick H. Brooke to renovate the triangular-shaped building into a clubhouse. The Sulgrave Club was added to the District of Columbia Inventory of Historic Sites in 1964 and the National Register of Historic Places in 1972. The building is also a designated contributing property to the Dupont Circle Historic District and Massachusetts Avenue Historic District.
The clubhouse is one of two remaining large houses on Dupont Circle, the other being the Patterson Mansion. The building was designed in the Beaux-Arts style, popular during the time of its construction. The clubhouse includes a lavishly decorated Beaux-Arts ballroom while some of the other rooms feature different architectural styles, including an Arts and Crafts entrance and Colonial Revival reception area.
