Klosterkirche St. Märgen, Catholic parish and pilgrimage church in Sankt Märgen, Germany

Mariä Himmelfahrt is the parish and pilgrimage church of St. Märgen in the Black Forest, built from 1715 by Johann Mathis of Mittelberg in Vorarlberg. The church was consecrated on 28 and 29 April 1725. Its interior is known for the Rococo carvings of Matthias Faller, whose original figures were saved from the 1907 fire and replaced by copies between 1995 and 2002.

Founded around 1118 by Bruno von Haigerloch-Wiesneck, a Strasbourg canon, the monastery was served by canons from Toul who brought the Marian statue that became a pilgrimage image. After five fires, the fourth in 1704 led Abbot Andreas Dilger to rebuild from 1715 under architect Johann Mathis; the church was consecrated in 1725. A lightning strike on 12 September 1907 caused the fifth fire, and the church was restored in neo-Baroque style.

The church is known for the Rococo carvings of Matthias Faller, who lived in the monastery from 1735 to 1737 and 1741 to 1743, and later in the neighbouring "Neues Haus", today the Gasthaus Krone. His figures were rescued from the 1907 fire and replaced by copies between 1995 and 2002. The originals are displayed in the church.

The church stands in the centre of Sankt Märgen, on the Black Forest plateau south-east of Freiburg. The nave is entered from the west, with the choir and the former monastery buildings adjoining to the south-east. Visitors should allow time for the climb to the village, which lies at around 900 metres.

Matthias Faller lived three times in St. Märgen: from 1735 to 1737 and 1741 to 1743 in the monastery, and from 1771 until his death in 1791 in the neighbouring "Neues Haus", today the Gasthaus Krone. On 6 August 1735 Abbot Dilger noted in his diary the entry of the sculptor as a lay brother, giving him the name Floridus.
