The opera house was built in 1845-52 based on a plan drawn by Laves. Originally it served as the royal theatre, as the king considered the theatre in the Leineschloß too small. The new opera house is a classical style building with two large wings and a balcony with statues of famous poets and composers.
The balcony used to be open so that visitors could drive straight to the entrance in their carriages. Nowadays they can use the stairs to the underground car park. Hannover's opera house was badly damaged in the Second World War and rebuilt in 1948. In 1985 the acoustics were improved and between 1996 and 1998 the stage equipment was restored.
