Painted wooden sculptures in the monastery primarily served as images for the altar or for devotional purposes. This function is illustrated by two sculptures from the Romanesque and Gothic periods. The figure of a Madonna with Child, dating to around 1250, was likely used by the nuns of the young women’s convent in Müstair for contemplation. It is one of the few preserved artworks from that time.

Different in focus from the image of the Madonna and Child is a so-called Pietà from the second half of the 14th century, which depicts Mary mourning the death of her son.

In the Middle Ages, altarpieces were often placed on altars. These often featured movable side panels and are therefore also known as winged altars. They allowed a richly designed three-dimensional central image to be concealed on weekdays and solemnly revealed on feast days and high holidays.

In the dormitory, two wings of such a winged altar are on display. They likely date from around 1520 and are attributed to the sculptor Jörg Kändel. The narrative style of the depictions is typical of the Late Gothic period.

An extraordinary collection consists of the baroque sculptures by the sculptor Johannes Patsch. They originate from the former high altar of the monastery church, dating to around 1630. In 1878, the altar was replaced by a neo-Gothic ensemble, but the sculptures were preserved. Today, they represent one of the few surviving testimonies of Johannes Patsch's work.

Until the restoration is completed in 2026, the central image of the altar, the Madonna of the Rosary, can still be admired in the church. Other figures from the altar ensemble are exhibited in the dormitory museum, including the legendary church founder Charlemagne and the church's patron saint, John the Baptist.
