The Hungarian State Opera House is a neo Renaissance building located in central Budapest, on Andrássy út. Originally known as the Hungarian Royal Opera House, it was designed by Miklós Ybl, a major figure of 19th century Hungarian architecture.
Construction began in 1875, funded by the city of Budapest and by Emperor Franz Joseph. The opera house opened to the public on the 27 September 1884.
Before the closure of the "Népszínház" in Budapest, it was the second largest opera building in the city; today it is the largest opera house in Budapest and in Hungary.
Many important artists have been guests here including the composer Gustav Mahler, who was director from 1887 to 1891 and Otto Klemperer, who was musical director from 1947 to 1950.
