The Lyceum Theatre is a Broadway theater at 149 West 45th Street, between Seventh Avenue and Sixth Avenue, in the Theater District of Midtown Manhattan in New York City. Opened in 1903, the Lyceum Theatre is one of the oldest surviving Broadway venues, as well as the oldest continuously operating legitimate theater in New York City. The theater was designed by Herts & Tallant in the Beaux-Arts style and was built for impresario Daniel Frohman. It has 922 seats across three levels and is operated by The Shubert Organization. The facade became a New York City designated landmark in 1974, and the lobby and auditorium interiors were similarly designated in 1987.
