Staatstheater Braunschweig, Opera house and theatre in Brunswick, Germany.

Staatstheater Braunschweig is a neoclassical theatre complex whose main venue, the Grosses Haus on Steinweg, opened in 1861. The photograph shows an L-shaped building in light grey stone on a rusticated base, with two storeys of tall rectangular windows, the upper row arched, pale green metal roofs and a columned portico with a wide staircase at the right end of the short wing. The building borders a paved street and a wooded park.

The theatre traces its origins to the Opernhaus am Hagenmarkt, founded in 1690 by Duke Anthony Ulrich. That house staged premieres of Lessing's Emilia Galotti in 1772 and Goethe's Faust I in 1829, was raised to a national theatre in 1818, closed in 1861 and demolished in 1864. The present Grosses Haus opened on 1 October 1861 after five years of construction; rebuilt under Daniel Thulesius, it reopened on 25 December 1948 with Mozart's Don Juan.

This theatre serves as a main venue for opera, drama, and concerts in the city. The performances range from classical works to contemporary productions and draw regular audiences from the surrounding region.

The Grosses Haus seats 896 with 60 standing places; the Kleines Haus holds up to 297 in a flexible layout. In summer a temporary open-air stage with about 1,200 seats is built on Burgplatz. The Grosses Haus stands on Steinweg, the Kleines Haus opposite on Magnitorwall.
