The Concert Hall was built in 1888 by AL van Gendt, who managed to engineer its near-perfect acoustics. Bernard Haitink, former conductor of the Royal Concertgebouw Orchestra, remarked that the world-famous hall was the orchestra's best instrument. Free half-hour concerts take place Wednesdays at 12.30pm from September to June; arrive early.

　　Those aged 29 or younger (ID required) can queue at the box office for €16 'Sprint' tickets one hour prior to shows. Guided tours in English (€11, 75 minutes) show that, in spite of Van Gendt's limited musical knowledge, he gave the two-tiered Grote Zaal (Main Hall) acoustics that are the envy of sound designers worldwide, along with a baroque trim, panels inscribed with the names of classical composers, a massive pipe organ and a grand staircase via which conductors and soloists descend to the stage.
