Schlosstheater Celle

The Castle Theatre in Celle is the court theatre which was established between 1670 and 1674/75 on the initiative of the opera lover, George William, Prince of Lüneburg from the House of Brunswick and Lüneburg, as part of the refurbishment and baroque restyling of Celle Castle. This baroque theatre, which fell into disuse and neglect for a while, was comprehensively renovated in 1935 with a horseshoe-shaped auditorium in the Italian style and is one of the oldest theatre buildings in Europe.

The stalls and two circles of the auditorium, the second gallery being an 18th-century addition, has a total of 330 seats.
