This striking baroque-meets-contemporary concert hall is the home of the Wiener Sängerknaben (Vienna Boys' Choir), who previously only performed at the Hofburg. Besides Friday-afternoon choral sessions at 5pm with the angelic-voiced lads, the venue stages a top-drawer roster of dance, drama, opera, classical, rock and jazz performances.

The acoustics are second to none in the 400-seat auditorium and there's a cafe where you can grab a drink before or after a show.
