Dreimäderlhaus, Protected town house in Innere Stadt, Vienna, Austria.

The Dreimäderlhaus is located at the corner of Schreyvogelgasse and Mölker Steig with a T-shaped design and two stories featuring ornate upper floor windows. The side wing displays a trapezoid gable crowned with an oculus window and a painted medallion showing the Holy Trinity.

The house was built in 1803 or in the third quarter of the 18th century in Josephinian style and renovated in 1950. It stands on the ramp to the Mölker Bastei, part of Vienna's former city fortifications. The name comes from a legend about Franz Schubert and the three daughters of glazier Franz Tschöll, invented by Rudolf Hans Bartsch for his novel Schwammerl.

The building's name comes from a story about composer Franz Schubert and three daughters of a glazier, which was later adapted into theatrical works. This fictional tale remains connected to how people understand the place today, even though the story itself never happened.

The building now houses the Ludwig Reiter shoe manufacturer and remains visible from the street for visitors to view. Its original architectural elements have been preserved through official protection measures maintained since 1950.

The nickname comes from Rudolf Hans Bartsch's 1912 novel Schwammerl, which invented a romance between Franz Schubert and the three daughters of glazier Franz Tschöll, called Hannerl, Hederl and Heiderl. The novel was adapted into the Singspiel Das Dreimäderlhaus and two films, in 1918 and 1958. The house itself has no connection to Schubert.
