After a period of decline in the sixteenth century, several German monks helped to restore and expand the abbey. Abbot Mathias Lang (1615–40), from Weingarten Abbey, reformed it, and in 1634 Marienberg joined the Benedictine Congregation of Swabia. Lang's successor, Jacob Grafinger (1640–53), enlarged the library, and made the younger members finish their education at schools of repute. In 1656 the abbey was again burned down. Abbot Johann Baptist Murr (1705–32) in 1724 founded a humanistic high school in Meran which is still administered by the monks of Marienberg. Abbot Placidus Zobel (1782-1815) compiled a chronicle of the abbots. In 1807 Marienberg was dissolved by the Bavarian government, but was restored by Emperor Francis II in 1816. Today the monks specialise in adult education: weekend courses and longer retreats are held at the abbey. The abbey itself is available for tours.
