Wallfahrtskirche Hafnerberg, Catholic pilgrimage church in Altenmarkt an der Triesting, Austria

The Wallfahrtskirche Hafnerberg is a baroque pilgrimage church on the Hafnerberg in Altenmarkt an der Triesting. Its high altar, oratories and pulpit were made in 1743–1745 after designs by Balthasar Ferdinand Moll, court sculptor to Maria Theresia, and executed by Johann Joseph Resler. The dome fresco of the Assumption of Mary is by Josef Ignaz Mildorfer.

A Marian column was erected here in 1653, marking an early point of devotion at this location. Construction of the current church began in 1729 under the direction of architect Daniel Christoph Dietrich, transforming the site into the baroque structure visible today.

The church owes its existence to the Via sacra, the pilgrim route from Vienna to Mariazell, and its patronal feast is celebrated on 15 August, the Assumption of Mary. The Marian column that Pankraz Reichhard had erected in 1653, together with its image of grace, still stands behind the tabernacle of the high altar.

The church stands on the Hafnerberg above Altenmarkt an der Triesting, on the Via Sacra pilgrim route from Vienna to Mariazell. Its patronal feast is celebrated on 15 August, the Assumption of Mary. Visitors coming by car should note that the building sits on the hill, not in the valley village, so the final approach is uphill.

The organ was commissioned from Johann Hencke, who designed it, but completed by his son-in-law Anton Pfliegler after Pfliegler married Hencke's daughter Ursula on 11 May 1766 and took over the workshop. It was consecrated on Sunday 26 July 1767; in 2019 Orgelbau Linder restored it, reconstructing lost stops, the bellows and the key coverings.
