The Order of the Teutonic Knights was a German society founded in 1190 in the Holy Land. The order came to Vienna in 1205, and the church dates from 1395. The building never fell prey to the baroque madness that swept the city after the Counter-Reformation, so you see it pretty much in its original form, a Gothic church dedicated to St. Elizabeth. The 16th-century Flemish altarpiece standing at the main altar is richly decorated with woodcarving, gilt, and painted panel inserts. Many knights of the Teutonic Order are buried here, their heraldic shields still mounted on some of the upper walls.

In the knights' treasury, on the second floor of the church, you'll see mementos such as seals and coins illustrating the history of the order, as well as a collection of arms, vases, gold, crystal, and precious stones. Also on display are the charter given to the Teutonic Order by Henry IV of England and a collection of medieval paintings. A curious exhibit is the Viper Tongue Credenza, said to have the power to detect poison in food and render it harmless.
