Neue Burg, Neoclassical palace in Innere Stadt, Vienna, Austria

The Neue Burg is the youngest wing of the Hofburg, a Neoclassical building with a pale stone facade that curves from the left toward a taller central section. The left wing has tall arched windows on the ground floor and a colonnade of plain columns above; the right section is more ornate, with paired columns, a large dark arched entrance, and a roofline topped by a bronze eagle on a globe flanked by figures, with three winged statues on the cornice below.

Construction of this imperial palace extension began in 1869 under Emperor Franz Joseph I and continued until 1923, involving architects Gottfried Semper and Carl von Hasenauer. The project was part of a larger redesign of the Hofburg imperial residence and reflected the late Habsburg monarchy's ambitions.

The Neue Burg houses the Weltmuseum Wien, the Ephesos Museum, the Collection of Historic Musical Instruments and the Imperial Armoury of the Kunsthistorisches Museum, plus the Papyrus Museum and the House of Austrian History of the Austrian National Library. The Ephesos Museum displays finds from the Austrian excavations at Ephesos, and the armoury grew out of the imperial collections.

The Neue Burg closes the southeastern side of Heldenplatz, a short walk from the Ringstrasse and the twin Kunsthistorisches and Naturhistorisches museums. Inside, the Weltmuseum, the Ephesos Museum, the collection of old musical instruments and the Hofjagd- und Rüstkammer are reached from the entrance under the eagle-topped central section. The building also serves as a Hofburg conference centre, so some rooms may be closed for events.

The foundations had to be dug up to 25 metres deep because the site lay on the loose ground of former city moats and underground defences. Porous Leitha limestone from Winden am See was used for them, while the base came from Duna-Almás near Esztergom and the facing from Marzana in Istria and the island of Brač.
