It has four facades, those on the north and south and on the east and west respectively being counterparts. It was begun in 1871, and the S. portion was occupied by the state depart- ment in 1875. The war and navy departments still occupy plain brick structures, which are to be taken down to give place to the new building.

Among the princi- pal buildings not belonging to the government are the masonic temple, odd fellows' hall, and Lincoln hall, which contains the library and reading room of the young men's Christian as- sociation. The Corcoran art gallery occupies a fine building near the white house. It was conveyed to a board of trustees for the ben- efit of the public in 1869 by W. W. Corcoran, a Washington banker.
