Ever since Tchaikovsky presided over the neo-Renaissance structure's 1891 debut, Carnegie Hall has been the best-known concert venue in the U.S. Comprising three halls, it's primarily a classical-music venue, showcasing the greatest soloists and orchestras in the world. The big names fill the main Isaac Stern Auditorium, and younger artists often debut in the facility's Weill Recital Hall. Jazz and new music are often featured in the underground Zankel Hall, which opened in 2003. The Rose Museum, which has exhibits of the hall's history and archival treasures, is open daily 11 am-4:30 pm (admission is free; closed 1 July-14 September). One-hour tours of Carnegie Hall are offered September-June Monday-Friday at 11:30 am and 2 and 3 pm. Tours are US$9 adults, US$6 seniors and students, US$3 children younger than 12. Purchase tickets at the box office 11 am-3 pm on tour days (no advance reservations needed).
