Maria Steinbach, Catholic pilgrimage church in Legau, Germany.

Maria Steinbach is a Rococo pilgrimage church built from 1749 under Abbot Ignatius Vetter of Rot an der Rot, with construction led by Benedikt Stadelhofer, and consecrated in 1755. Its west facade is richly articulated, and inside curved galleries bulge into the nave. The side-aisle vault frescoes depict miracles of the Steinbach Madonna, and the pulpit, side altars and high altar were made by Wessobrunn stuccoist Johann Georg Üblhör, completed after his death in 1763 by Franz Xaver Feuchtmayer the Younger.

A first church in Steinbach is documented in 1181, when knight Berthold von Laupheim exchanged estates with Rot an der Rot Abbey. A late Gothic replacement was begun in 1510 under Abbot Konrad Ehrmann and consecrated in 1519. After a reputedly miraculous image of Our Lady of Sorrows drew crowds, the present Rococo church was begun in 1749 under Abbot Ignatius Vetter, consecrated in 1755, and its interior completed around 1765.

Pilgrims come for two devotions: the Sorrowful Mother statue on the left side altar and the Holy Cross relic given in 1723 by Abbot Hermann Vogler. On the feasts of the Finding of the Cross (3 May) and the Exaltation of the Cross (14 September), cross water is blessed with the relic. A nearby museum displays votive tablets and letters of thanks from centuries of pilgrimage.

A penitential path with several small chapels leads up to the church from Lautrach and from Legau. The church stands on a hill visible from afar at the border between Upper Swabia and the Allgäu. A Baroque well house with a figure of Saint Ulrich stands below the church.

The two pilgrimage traditions meet in one object: the particle of the Holy Cross that Abbot Hermann Vogler of Rot an der Rot gave the community in 1723, kept in a reliquary. On Kreuzauffindung (3 May) and Kreuzerhöhung (14 September) it is still used to bless Kreuzwasser.
