Neusimmering Church, Roman Catholic parish church in Simmering, Austria

Neusimmering Church is a Roman Catholic parish church located at Enkplatz in Simmering, Vienna, designed in Romanesque Revival style. The building features twin towers reaching 56 meters high and provides interior seating space for approximately 2800 worshippers.

Construction took place between 1907 and 1910 under architect Hans Schneider's direction, with the building consecrated shortly after. Emperor Franz Joseph I. attended the dedication ceremony to bless the newly completed structure.

The high altarpiece, painted by Leopold Kupelwieser in 1833 for Klosterneuburg Abbey, was moved here in 1958. It shows the Birth of Mary, with Saint Augustine kneeling at lower left and Saint Leopold at lower right; a medallion between them bears the prophet Isaiah and the Latin inscription "Virgo concipiet et pariet".

The main entrance is on Enkplatz, where the twin-tower facade faces the square; the side aisles and the 53-metre-long nave are entered from the portal porch. The church is a protected monument and an active parish of the Resurrectionists, so visits fit around services. The site is level and reachable by public transport to Enkplatz.

The church's reinforced concrete structure was executed by Ignaz Gridl, the Imperial and Royal Court locksmith and iron constructor. The main nave spans 15 metres and rises 19.65 metres, while the three aisles together measure 23.5 metres wide and the interior reaches 53 metres at its longest point.
