Sankt Xaver, Jesuit Catholic parish church in Leoben, Austria.

Sankt Xaver is a former Jesuit church and today the Roman Catholic parish church of Leoben. Built from 1660 to 1665, it has a massive early Baroque exterior and an interior that has remained almost unchanged since the 17th century. The high altar and furnishings are original to the period.

The Jesuit college in Leoben was founded after Ferdinand II donated his city castle to the order; two priests arrived from Graz on 10 December 1613. Construction of the church began in 1660, 47 years later, funded largely by the Vordernberg forge master Christoph Jantschitsch, and was completed in 1665. After the Jesuit order was dissolved in 1773 the church was no longer used, and in 1811 it was declared the official town parish church.

The church is dedicated to Francis Xavier, co-founder of the Society of Jesus, whose name it bears. Its interior has kept the 17th-century furnishings almost unchanged, so visitors see the original early Baroque altars and decoration rather than later remodelling.

The church is located at Kirchplatz 1 in central Leoben and is easy to find in the city center. For questions about opening hours or events, you can contact the parish office.

The church owes its survival largely to money: its lavish size and decoration made later modernisations in the late Baroque and purist 19th century too costly, so the early Baroque interior with its period furnishings stayed in place. The building was begun 47 years after the Jesuit college was founded in Leoben.
