Paramount Plaza; the other is the Circle in the Square Theatre in the building's basement. The Gershwin, Circle in the Square, Minskoff, and American Place theaters were all constructed under the Special Theater District amendment of 1967 as a way to give their respective developers additional floor area. The Gershwin was decorated in what Alswang described as an Art Nouveau style. The theater covers and has bronze velour decorations throughout its major public spaces. Originally decorated in white and gold, the Gershwin was redecorated in a blue-and-white color scheme in 1993. The theater is operated by the Nederlander Organization. Lobbies and Hall of Fame At the base of Paramount Plaza is a promenade that connects 50th and 51st Streets, providing entry to the Gershwin and Circle in the Square theaters. There are marquees for the theaters' entrances on both 50th and 51st Streets. The box office is at ground level. Escalators lead from the ground floor to the Gershwin Theater. The names of 90 celebrities who were active between 1860 and 1930 are inscribed in bronze-gold lettering along the escalators. The second floor contains the American Theater Hall of Fame, where the names of notable theatrical personalities are inscribed in gold letters. Eligible inductees have had a career in American theater for at least 25 years and at least five major Broadway production credits. The lobby contains a white wall behind the orchestra seats and measures wide. The Hall of Fame's names stretch across the four-story-high wall of the lobby. The theater also has two rotundas, one of which originally contained the music and theater collections of the Museum of the City of New York. The hall's names stretch into the rotundas. Auditorium Playbill cites the theater as having 1,926 seats, while The Broadway League gives a figure of 1,933 seats. The Gershwin's seats are spread across two levels: an orchestra with about 1,300 seats and a smaller mezzanine with about 600 seats. This was based on Alswang's observation that most people wanted orchestra seats. The seats in the Gershwin are spaced apart from row to row, compared to in older theaters where each row was only apart. The balcony has 14 rows. Like traditional Broadway houses (and unlike the contemporary Minskoff Theatre), the theater had aisles in the center and along the sides. The orchestra level is ADA-accessible via an elevator from the ground story. The mezzanine level has
