Pörtschach am Wörthersee is a municipality in the district of Klagenfurt-Land in Carinthia, Austria. It is an established summer resort and lakeside town on Wörthersee. A growing tourism industry started in the mid-19th century, accelerating after the establishment of the Lake Wörth navy in 1853. Shortly after that, in 1864, Pörtschach received a railway station on the new Southern Railway line from Vienna to Venice; this made it a favored tourist destination. Famous tourists from Vienna included Emperor Franz Josef I of Austria, Gustav Mahler, and Johannes Brahms, who worked on his Second Symphony and Violin Concerto here.

In the late 19th and early 20th century, numerous villas were erected in the so-called Wörthersee style, according to Friedrich Achleitner a mix of Art Nouveau, German Romanticism, Baroque, and mansion architecture. Franz Baumgartner, Wilhelm Heß, Josef Victor Fuchs, and Carl Langhammer were the most important representatives of this specific building style.
