Church of Mariahilf, Parish church in Mariahilf, Austria

The Church of Mariahilf is a Baroque parish church at Mariahilfer Straße, corner Barnabitengasse, with a west facade facing the street, two towers roofed in copper between 1721 and 1726, and a nave rebuilt from 1711 to 1715 by Franziskus Jänckl. Inside are six chapels and ceiling frescoes on the Life and Glorification of Mary by Josef Hauzinger and Franz Xaver Stratmann, pupils of Paul Troger.

The church began in 1656 as a cemetery church for the Michaelerkirche; in 1660 the Barnabite Don Cölestin Joanelli donated the Mariahilf image, a copy of Lucas Cranach's original. After Ottoman troops destroyed the 1668/1669 stone chapel in 1683, Sebastian Carlone the Younger and mason Ambrosius Ferrethi rebuilt it in 1686–1689, consecrated on 14 August 1689. From 1711 Franziskus Jänckl remodelled it into its present form, with the west facade towers roofed in copper between 1721 and 1726.

The name Mariahilf comes from the miraculous image donated by the Barnabite Cölestin Joanelli in 1660, a copy of Lucas Cranach's painting in Innsbruck Cathedral. The sacristan carried it to St. Michael's for safety during the 1683 siege. The pulpit, designed by Antonio Beduzzi in 1720 and remodelled in 1794, shows Christ crowning St Paul, patron of the Barnabites.

This place of worship sits in a central neighborhood and is easy to reach on foot. Visitors can walk through during the week, though it is important to respect the times when services take place.

The organ case from 1763 by Johann Hencke is still in use, though the instrument's interior was largely rebuilt by Johann M. Kauffmann in 1894 with 24 registers. Its prospect displays 97 sounding and 48 blind pipes, a detail visible from the gallery.
