Schönlaterngasse is a small winding alleyway in central Vienna. In the Middle Ages it was known as Straße der Herren von Heiligenkreuz, as it passes the Heiligenkreuzer Hof. Later on, it carried several names that still referred to the Heiligenkreuzer Hof before being named after the "beautiful lantern" in 1780. The buildings along the alley date back to Baroque times.
Schönlaterngasse originally terminated in an alleyway that was removed to make way for the Jesuitenkirche, upon which it was lengthened to Postgasse, where it still ends today.
