Palais Rothschild, City palace on Prinz-Eugen-Straße, Wieden, Vienna, Austria

Palais Rothschild at Prinz-Eugen-Straße 26 in Vienna's fourth district, Wieden, is a four-storey neobaroque former residence designed by the theatre architects Ferdinand Fellner and Hermann Helmer and built in 1894. It was the second Palais Rothschild commissioned by Baron Albert von Rothschild, smaller than his Palais Albert Rothschild at Prinz-Eugen-Straße 20-22, which was demolished in 1954. Since 1987 the building has belonged to the Brazilian state and houses its embassy.

It was the second Palais Rothschild commissioned by Baron Albert von Rothschild, built in 1894 by the theatre architects Ferdinand Fellner and Hermann Helmer on Prinz-Eugen-Straße, the same street as his larger Palais Albert Rothschild at number 20-22. After the Anschluss, the Nazis seized the Jewish-owned property, the Rothschilds fled Austria and the palace was plundered of its ornaments and artifacts, though it survived without structural damage. Since 1987 the Brazilian state has owned it.

The building is known as the "small" Palais Rothschild, to distinguish it from the larger Palais Albert Rothschild at Prinz-Eugen-Straße 20-22, which was demolished after the war. Since 1960 the Brazilian foreign ministry has rented it as the ambassador's residence and a cultural centre, and in 1987 the Brazilian state bought it from the Rothschild heirs.

The building at Prinz-Eugen-Straße 26 in Wieden is not a museum open to the public: it has housed the Brazilian embassy since 1987, when the Brazilian state bought it from the Rothschild heirs. Visitors can view the four-storey neobaroque facade from the street; interior access depends on embassy business.

The building is often confused with the larger Palais Albert Rothschild at Prinz-Eugen-Straße 20-22, which was demolished in 1954; this smaller palace at number 26 survived intact. Since 1987 it has belonged to the Brazilian state, which bought it from the Rothschild heirs after renting it from 1960 as the ambassador's residence and cultural centre.
