Gothic Hall Church on the Market Square. In 1543 the Reformation in Osnabrück began in this protestant Lutheran market church. It is a place of calm in the centre of the city and invites you to services and concerts. The triumphant cross and the crucifixion group (13th century), the passion cycle by Albrecht Dürer(1510), the winged altar (1515), the font (1560), the Schreiter window (1992) are worth seeing.
