The wing was built during the presidency of Theodore Roosevelt (1901-1909) as an entrance for formal and public visitors. Its main feature was the long cloakroom for storing the coats and hats of the visitors. It was significantly expanded in 1942, primarily to cover the construction of an underground bunker, now the Presidential Emergency Operations Center. During this renovation, the cloakroom became the movie theatre, and later renovations added further offices.
