Zelle Abbey, Former Augustinian canons' monastery in Zelle, Aue-Bad Schlema, Germany

Zelle Abbey is a former Augustinian monastery in Aue featuring a stone church with architectural elements reflecting the Romanesque and Gothic styles of medieval central Germany. The monastery complex includes various structures that were expanded and modified over the centuries.

The Meinheringer family founded the Augustinian canons' monastery near the confluence of the Zwickauer Mulde and Schwarzwasser in the second half of the 12th century; Emperor Frederick I confirmed it on 7 May 1173 in Goslar, dedicating it to Saint Andrew and the Holy Trinity. It was sacked in the German Peasants' War in 1525, dissolved in 1527 during the Reformation and sold for 800 guilders to the Saxon elector, after which it served as a manor. The former monastery church became a daughter church of Oberschlema in 1533, gained its own Lutheran parish in 1879, and was replaced by the Friedenskirche in 1914.

The monastery church, dedicated to the Virgin Mary, holds two oval marble grave slabs with ear-of-wheat ornament for the estate owner Carl Erdmann von Brandenstein and his wife, dating from the 1820s, placed before the altar. A painted 18th-century crypt lies northeast beneath the choir, and a Baroque patron's box with twelve painted scenes from Christ's life lines the north interior wall.

The former monastery church stands in Zelle, now part of Aue-Bad Schlema, near the confluence of the Zwickauer Mulde and Schwarzwasser. Since 1914 it has served as a burial chapel, so it is not a regular parish church open for services. A support association founded in 1994 has worked on its restoration, including the roof, tower and bell frame in 1998 and the interior from 2002 to 2004.

The weather vane on the roof turret, renewed in 1998, bears the inscription SOLI DEO GLORIA / 1173 * 1998, linking the 1173 founding charter of Emperor Frederick I to the church's restoration. Inside, a cupboard painted with a chequerboard pattern may be a Romanesque host cupboard.
