Wallfahrtskirche zu den Sieben Schmerzen Mariä, Pilgrimage church on Pöstlingberg hill, Linz, Austria.

The Wallfahrtskirche zu den Sieben Schmerzen Mariä is a late-Baroque cross-domed church with a circular central space covered by a pendentive dome, built from 1742 to the plans of Johann Matthias Krinner. Its white and pale pink double-tower facade faces Linz, the tower helms are black, and the right transept wall shows the bare-stone style of the Mühlviertel. A two-arm stair leads to the portal terrace.

The pilgrimage began on 29 November 1716, when the Capuchin lay brother Franz Anton Obermayr carried a Mater Dolorosa figure by the Linz sculptor Ignaz Jobst up the Pöstlingberg and set it at a weather cross. From 1720 it drew pilgrims, and the Starhemberg counts funded a church built from 1742 to plans by Johann Matthias Krinner. The image entered the completed choir in 1747; the church was consecrated in 1748 and became a parish church in 1786. Pope Paul VI raised it to a minor basilica in 1964.

The patronal feast of the Seven Sorrows of Mary is celebrated on 15 September. The pilgrimage began with the Maria Pöstlingberg Vesperbild, a Mater Dolorosa carved by Linz sculptor Ignaz Jobst, which lay brother Franz Anton Obermayr carried up the hill on 29 November 1716 and set at a weather cross. A fresco on the left longitudinal facade shows Obermayr carrying the image into the newly built church.

The church stands on the Pöstlingberg summit; the Pöstlingbergbahn rack railway and bus lines run up from Linz-Urfahr. The entrance portal is reached by a two-arm staircase, with a small terrace in front of it. The forecourt with balustrade dates from 1937. The patronal feast of the Seven Sorrows of Mary is celebrated on 15 September.

The 2022 organ by Freiburger Orgelbau Hartwig und Tilmann Späth was designed by artist Valie Export and inaugurated on 12 March 2023 by Bishop Manfred Scheuer. It carries a broad metal band with the sentence "Wer begreift, hat Flügel." Some pipes from the 1942 organ were reused by Export for her installation "Oh Lord, Don't Let Them Drop That Atomic Bomb on Me" at Kunsthaus Bregenz.
