The Perry Belmont House, sometimes referred to as the International Temple of the Order of the Eastern Star, though there are no ritual or ceremonial spaces in the building, is the world headquarters of the General Grand Chapter of the Order of the Eastern Star, one of several organizations affiliated with Freemasonry.

[4] The house takes the form of a free-standing pavilion in the French style, with a single storey articulated with slender Ionic pilasters over a channel-rusticated basement.

In 1919, Edward, Prince of Wales, was a guest of the Belmonts (at President Woodrow Wilson's request); there he handed out medals to various American soldiers whom Great Britain wished to honor for their roles in World War I.

Beginning in the 1920s, the Belmonts spent increasing amounts of time away from Washington, and the house was mothballed for almost a decade.

[9] The building serves as the headquarters for the General Grand Chapter of the Order of the Eastern Star.
