Wallfahrtskapelle Klein Maria Dreieichen, Pilgrimage chapel in Hollabrunn, Austria

The Wallfahrtskapelle Klein Maria Dreieichen is a chapel with a three-sided apse and pointed-arch windows, its facade divided by pilaster strips and featuring a classicist portal riser. It was built in 1869 by master builder Johann Gassalek using Zogelsdorf stone, and the altar stands over the rootstock of the three-trunked oak. The chapel is dedicated to the Sorrowful Mother of God.

The chapel emerged from a location where a Marian image was placed on a three-trunked oak tree between 1784 and 1800, marking a pilgrimage site that drew believers for generations. The religious image itself has an even older history and was eventually transferred to this location.

The site draws pilgrims from the surrounding region who come to honor Mary and maintain the tradition of devotion at this sacred location. The chapel stands as evidence of popular faith that continues to be practiced by the local community.

The chapel stands by the road near Groß, with devotional stalls and food and drink stands set up around it. A sacristy added in 1931 and consecrated on 4 October allows confessions to be heard on site. The site is cared for pastorally by Stift Altenburg, and the main festivals are celebrated at the Seven Sorrows of Mary and Ascension.

The Pietà now in the chapel is not the original: the late-Gothic wooden Pietà transferred here on 28 August 1870 is kept in the Museum Hollabrunn. It had been found undamaged in 1640 among the ruins left by Swedish troops in Groß. A fire at the altar in 1908 destroyed the carved wooden statue, while the image of grace survived.
