Pfarrkirche Mülln, Parish church in Mülln district, Salzburg, Austria

Pfarrkirche Mülln is a parish church in the Mülln district of Salzburg, positioned on the northern extension of Mönchsberg mountain. The building features a tall tower with a distinctive helm and double-lantern spire, while the interior is designed in Baroque style.

A chapel in Mülln was first mentioned in 1148, when Archbishop Gebhard had the altar of the Marian chapel renewed; a Romanesque crucifix from that period survives. Archbishop Johann II von Reisberg began a new Gothic hall church in 1439, built by Ulrich Dankl and Heinrich Murauer and consecrated in 1453. It became a parish church shortly after 1460, when Archbishop Burkhard von Weißpriach separated Mülln and Maxglan from the cathedral parish. Archbishop Wolf Dietrich von Raitenau rebuilt it and gave it to the Augustinian Hermits in 1605; it was baroquised in the 18th century.

The church is dedicated to the Assumption of Mary, celebrated on 15 August. Its high altar, designed by the Vienna painter Vinzenz Fischer in 1758–1760 with figures by Lorenz Wieser, frames the late-Gothic statue of the Madonna of Mülln, carved around 1453 and attributed to Jakob Kaschauer. The four canvases above the chapel entrances are by Vinzenz Fischer.

The church stands at Augustinergasse 4 on the northern spur of the Mönchsberg, at the northeastern edge of Salzburg's historic centre. Walkers crossing the Mönchsberg can visit it at the start or end of the route. The Müllner Bräustübl brewery and tavern is next door.

The church tower, essentially late Gothic, was given its present form in 1674 under Max Gandolf von Kuenburg: he had it remodelled and topped with a Baroque double lantern, and the east and west sides carry his coats of arms. The tower's three- and four-part Romanesque-style sound arcades are a detail to look up for.
