The centre where the triple-sized orchestra of the Opera, the first and largest philharmonic ensemble in Hungary, rehearses for performances, galas and its own concerts, is located in Jókai Street near the Oktogon, not far from the Opera House.
Opposite the side entrance in Hajós Street, there is a block of flats designed by Miklós Ybl with Károly Lotz’s and Jahn József frescos under the entrance.
Before the refurbishment of the Opera House in 1980, a 12-storey building was constructed opposite the artists’ entrance in Hajós Street. The building, with its more than 4,000 square metres, was built in place of a demolished tenement, and it houses several offices, dressing rooms and rehearsal rooms of the institution.
