Reduta Theatre, Theatre building on Zelný trh in Brno, Czech Republic

Reduta Theatre is a theatre building on Zelný trh in Brno, first mentioned in 1608 and the oldest theatre building in Central Europe. Its auditorium, built in 1733 in the east wing, has an elliptical plan with two balconies and a capacity of 325 spectators. The building also contains the Mozart Hall and a café.

Brno bought the run-down Liechtenstein palace on Zelný trh around 1600 and turned it into a tavern; the building is first mentioned in 1608. A dedicated theatre with boxes and a deep perspective stage was built in its east wing in 1733, and the theatre opened on 28 November 1733. Fires in 1785 and 1786 led to a neoclassical rebuild, and after 1918 the former German theatre alternated Czech and German productions.

The name Reduta comes from the German word for a hall used for balls and concerts, reflecting its 18th-century role as a venue for festive events. Since 2005 the building has housed the National Theatre in Brno's drama company, and it has no permanent ensemble, so guest artists from the Czech Republic and Slovakia perform here.

The building sits in the center of town at Zelný Square and is easy to reach on foot. Check the schedule before visiting, as performances and opening times change regularly throughout the year.

The 30 December 1767 concert by the eleven-year-old Mozart and his fifteen-year-old sister Nannerl was recalled by Šternberk provost Aurelius Augustin, who noted that the boy could not stand the trumpets because they played out of tune with one another.
