The first statue was placed in 1870. By 1971 all 50 states had contributed at least one statue, and by 1990 all but five states had contributed two statues. Initially all of the state statues were placed in National Statuary Hall. As the collection expanded, however, it outgrew the Hall, and in 1933, Congress authorized the display of the statues throughout the building for both aesthetic and structural reasons. Presently, 38 statues are located in National Statuary Hall.
