Palais Esterházy, Baroque palace in Innere Stadt, Austria

Palais Esterházy is a Baroque palace in Vienna's Innere Stadt featuring symmetrical architecture with an ornate facade decorated with elaborate stonework and large windows spanning multiple floors. The building houses various commercial tenants today and functions as a mixed-use structure.

Construction of Palais Esterházy began between 1685 and 1695 under the direction of the first prince of the Esterházy family. The building was created by consolidating fourteen separate properties into a single representative residence.

The Esterházykeller occupies wine cellars that trace back to the medieval Hungarian House on this site; the tavern opened around 1808 and has changed little since. The palace chapel, consecrated in 1699 to St Leopold, held a two-storey hall where Joseph Haydn worked; it is still consecrated but no masses are held. The building now also hosts the Viennese branch of the Museum of Illusions.

The palace is located at Wallnerstraße 4 in Vienna's first district and is easily accessible by public transport. The interior spaces are partially open to visitors, particularly the historic cellar restaurant which is regularly open.

The palace chapel, consecrated in 1699 to St Leopold, has a two-storey hall, Baroque altars and an organ from around 1800; Joseph Haydn worked there. The chapel is still consecrated, but no masses are held. The Esterházykeller wine cellar, opened around 1808, traces back to the former Hungarian House.
