Palais Coburg

Palais Coburg is situated in Vienna, Austria, on a site that once formed part of the city\’s historic fortifications. The palace stands atop the Braunbastei, a bastion constructed in the mid-16th century as part of Vienna’s defensive walls.

The palace’s origins date back to the early 19th century when the land was owned by the Coburg family through the marriage of Ferdinand Georg August of Saxe-Coburg-Saalfeld-Koháry to Maria Antonia Gabriela von Koháry. In 1839, Viennese architect Karl Schleps designed the building, but after his death in 1840, construction was completed by master builder Adolf Korompay over the following five years. The palace was finished in 1845 but remained unoccupied until 1848. The following year, August of Saxe-Coburg and Gotha and his wife Clementine d’Orléans took up residence.

Throughout the 19th century, the palace served both as a noble residence and a rental property. While parts of the building were converted into apartments, the first floor was reserved for representative rooms adorned with the insignia of the French royal family and the House of Saxe-Coburg and Gotha. In 1864, a sculpted crown was added atop the central section of the façade, enhancing its stately appearance.

During World War II, Palais Coburg suffered damage from bombing in 1945. Following the war, Russian occupation forces were stationed there until 1955. Subsequently, the Austrian Federal Railways rented two floors of the building, a tenancy that lasted until 1997. The last private resident from the Coburg-Koháry lineage was Sarah Aurelia Halasz, who lived in the palace until her death in 1994, although she had sold the property in 1978. After financial difficulties led to bankruptcy, the palace passed to the Länderbank before being acquired by Viennese entrepreneur Peter Pühringer in 1997.

Between 2000 and 2003, the palace underwent extensive restoration to address significant deterioration. Today, it functions as a luxury hotel and office space. Notably, Palais Coburg hosted important international negotiations on Iran’s nuclear program, culminating in a landmark agreement on July 14, 2015, after three weeks of talks involving Iran, the European Union, the five permanent members of the UN Security Council, and Germany.
