Hungarian State Opera House
Jungfer made all the wrought iron works in Buda Castle, the new Hungarian Parliament Building, Hungarian State Opera House, Saint Stephen's Basilica, Keleti Railway Station, Vigadó Concert Hall and other city palaces. His most important work, the railing of Buda Castle, was destroyed during the Battle of Budapest, but it was faithfully restored in 1981. Many of his lesser works are kept in the Museum of Applied Arts in Budapest.
