Attention is called first to the group of monumental semipublic buildings, classical in design, on Seventeenth Street north of Constitution Avenue and along that Avenue from Seventeenth Street west to the Potomac River. It has been said that nowhere else in the world is there such a fine group of marble buildings. THE CORCORAN GALLERY OF ART This Gallery had its beginning in the year 1869. It ranks as one of the great art galleries in the United States. The present building (at New York Avenue and Seventeenth Street) was designed by Ernest Flagg, architect, and completed in 1897. It is built of Georgia marble. It houses rare masterpieces of painting and sculpture. THE AMERICAN NATIONAL RED CROSS Adjacent to the Corcoran Gallery on the south, the American National Red Cross occupies three large buildings constructed of Vermont marble. They were designed by Trowbridge & Livingston, architects, of New York City. The Red Cross had its beginning during the Civil War. In 1905 the organization was chartered by Congress along its present lines. There are 5,500,000 adult members and 8,500,000 Junior members (as of June 30, 1938). MEMORIAL CONTINENTAL HALL The next building to the south is the headquarters of the National Society of the Daughters of the American Revolution. It faces Seventeenth Street, was designed by Edward Pearce Casey, architect, built of Vermont marble, and completed in 1905. The cornerstone was laid April 19, 1904, the anniversary of the Battle of Lexington. On that date the organization holds its convention in Washington each year. It was founded October 11, 1890, and on February 1, 1938, numbered 142,744 members, with about 2,500 chapters in all parts of the United States. CONSTITUTION HALL Another of the Society’s buildings, facing Eighteenth Street, in this square, is the leading auditorium of the city. It was designed by John Russell Pope, architect, built of Alabama limestone, and completed in October, 1929. The auditorium seats 4,000 persons. On page 278 there is a picture of the building. The mural decorations of the interior are by J. Monroe Hewlett, architect. THE PAN AMERICAN BUILDING This building, at the corner of Seventeenth Street and Constitution Avenue, is considered by some to be the most beautiful in Washington. It was designed by Albert C. Kelsey and Paul P. Cret, architects, in the Spanish-classical style of architecture. It was built of Georgia marble and was dedicated April 26, 1910. It is the headquarters of the 21 Republics of the Pan American Union. In it is the famous Hall of the Americas. Andrew Carnegie contributed $850,000 toward the building, and the United States Government contributed the 5-acre tract, on which stood the Van Ness Mansion (1815) and the David Burnes cottage, which stood there in the days of George Washington.
