BUDAPEST.- This display presents Hungarian history through pictures and at the same time is closely linked to the reorganization of the 19th century permanent collection of the Hungarian National Gallery . Built primarily on historical paintings and portraits, the exhibition parades the finest works of Hungarian artistry through the lines of the National Anthem and Summons. The Hungarian National Gallery is the largest public collection documenting and presenting the rise and development of the fine arts in Hungary. It has operated as an independent institution since 1957. The HNG moved to its present location, the former Royal Palace of Buda, in 1975.
