House of the Teutonic Order, Medieval headquarters in central Vienna, Austria.

The House of the Teutonic Order at Singerstraße 7 is a Baroque complex of buildings grouped around two courtyards, with a pale grey stone facade of five storeys and twelve turquoise-framed windows on the upper floors. The ground floor has early Baroque barrel and cross vaults, and the sala terrena is decorated with late 18th-century frescoes showing figural ornament and mythological scenes. A stone archway opens over a dark wooden door beside a sign reading "DEUTSCH ORDENS RITTER".

The Teutonic Order settled on this site around 1222, and the house served as the seat of the Austrian bailiwick's land commander. From 1667, under land commander Gottfried Freiherr von Lamberta, the decayed convent buildings except the Gothic church were demolished and replaced by Carlo Canevale's new complex, extended in 1679–1682 and again in 1720–1725; a fourth storey followed in 1785. In 1809 Grand Master Anton Viktor of Habsburg moved the order's headquarters here from Bad Mergentheim.

The name refers to the knights who established the order's presence here centuries ago. Today visitors can see the different rooms that show how the order functioned and lived within these walls.

The building sits within walking distance of Stephansdom cathedral in the city center. Visitors can reach it easily using the U1 or U3 subway lines to Stephansplatz station or by taking buses that serve central Vienna.

The building once housed Wolfgang Amadeus Mozart and later Johannes Brahms at different times. These famous composers lived here and left their mark on Vienna's musical history.
