Steingaden Abbey, Romanesque monastery in Steingaden, Germany.

Steingaden Abbey is a former Premonstratensian monastery whose church, the Welfenmünster, is a white-plastered building with two tall square towers, each capped by a steep red pyramidal roof. The right tower carries a round clock face below three arched windows; between the towers a red hipped roof sits above two large arched windows with stone tracery. Of the convent buildings only the west wing survives, its ground floor holding nine Romanesque cloister bays vaulted in the Late Gothic period.

The monastery was founded in 1147 and went through several building phases over the centuries, moving from Romanesque through Gothic to later Baroque elements. Each of these phases left visible traces that can still be read in the fabric of the complex today.

The church's late-Gothic vestibule preserves a fragment of a Renaissance painting uncovered in 1951 on the north wall: the "Guelph Genealogy", tracing the House of Welf from Albert Azzo I, Margrave of Milan, to Welf VII, and showing the founding of Rottenbuch and Weingarten abbeys. Above the door, a large panel depicts the funeral procession of Duke Welf VI.

The former abbey church, the Welfenmünster, now serves as Steingaden's parish church and is the main interior space to visit. Of the monastic buildings, only the west wing survives, housing the parish house with the remains of the Romanesque cloister on its ground floor. The cemetery contains the grave of Dominikus Zimmermann, architect of the Wieskirche. The Johanneskapelle, a Romanesque rotunda, stands by the west entrance of the cemetery.

The carved sandstone panel of the Welf arms, made around 1193 and possibly part of the destroyed tomb of Welf VI and Welf VII, is the oldest surviving heraldic representation in Germany apart from seals. It was acquired by the Bayerisches Nationalmuseum in Munich in 1861. In the church, a metal plate in the central aisle marks the grave, and Johann Georg Bergmüller's fresco above the organ shows the two Guelphs.
