St. Michael's Church (German: Michaelerkirche), dedicated to the Archangel Michael, is one of the oldest churches in Vienna, Austria, and also one of its few remaining Romanesque buildings. Over time, there have been many alterations, resulting in its present day aspect, unchanged since 1792. This church, close to the Michaeler wing of the Hofburg, used to be the parish church of the Imperial Court (it was then called Zum heiligen Michael).
Over its long history, spanning more than eight centuries, this church has incorporated a medley of architectonic styles. The church is a late Romanesque, early Gothic building dating from about 1220-1240. There is a document giving 1221 as the foundation date of the church, but this is most probably a 14th century forgery.
