St. Augustine's Monastery, Augustinian friary in Erfurt, Germany

St. Augustine's Monastery is a 13th-century religious community in Erfurt featuring a church, courtyards, living quarters, and a library constructed from stone with Gothic architectural details. The ensemble demonstrates the building techniques of its era and served for centuries as a place of study and contemplation.

The monastery was founded in the 13th century and became an important center for theological study in the Middle Ages. The Reformation fundamentally changed its role, particularly through the presence of a young monk who spent formative years here developing his theological ideas.

The monastery church's choir windows include the Löwen- und Papageien-Fenster (Lion and Parrot Window), whose design is the model for the Luther rose, the seal Luther later used. The friary also had a Studium generale, an early form of university, led by the Augustinian Henry of Friemar the Elder (c. 1245–1340). Today the church hosts music concerts and the complex serves as a meeting and conference centre.

The monastery is open to visitors and offers guided tours, overnight stays, and spaces for religious gatherings throughout the year. Plan your visit ahead to learn about opening hours and which areas may have restricted access at certain times.

The monastery's church preserves stained glass windows made between 1310 and 1340, including the Löwen- und Papageien-Fenster in the choir, which contains the model for the Luther rose. The friary also had an outdoor pulpit, showing that sermons were preached to large crowds in the open air.
