The Palais Lanckoroński was a palace in Vienna, Austria, located at Jacquingasse 16-18, in the Landstraße District. It was constructed in 1894-95 for Count Karol Lanckoroński and his family as a personal residence, and it housed the count's enormous art collection. The palace was built in a neo-baroque style by the theatre architects Ferdinand Fellner and Hermann Helmer. The building was three stories high, set back from the street, and protected by a wall with double gates. The entrance hall was wood panelled, two stories high, and decorated with portraits of the family. Other festive halls were decorated with frescoes and luxurious gobelin tapestries from the 17th century. Precious paintings, furniture and sculpture from different eras were arranged to form themed ensembles in the various rooms, with the rooms named to reflect the collection housed within. The palace was severely damaged in World War II, and was torn down in the 1960s.
The noble Lanckoroński family, originally from Galicia, assembled a major art collection through the generations, including Italian Renaissance paintings as well as German, French, and Dutch pictures, antique sculptures, bronzes, glass miniatures and porcelain. Count Karol Lanckoroński continued his family’s interest in the collection. He was a collector, archaeologist, art patron, author and conservator and also served as chamberlain to emperor Franz Joseph I. His additions to the collection included antique sculptures, as well as paintings by Tintoretto, Canaletto and Rembrandt. The art collection in the Lanckoroński Palais became one of the largest in Vienna under his stewardship. Frequent visitors to the palace were the artists Hans Makart, Viktor Oskar Tilgner, Arnold Böcklin, Kaspar von Zumbusch and Auguste Rodin. Writers and authors such as Hugo von Hofmannsthal and Rainer Maria Rilke also paid visits. After the end of the Austro-Hungarian Empire, the Count decided to return to Poland and began to move a large part of his collection to the family’s ancestral estate in Galicia.
