Maulbronn, the former Cistercian monastery, is considered to be the most completely preserved monastery complex from the Middle Ages north of the Alps. Since its inscription in the UNESCO List of World Cultural Heritage Sites in 1993, it has been one of the most frequently visited cultural monuments in Baden-Württemberg. The Silver Grey Guide outlines the history of the Cistercian monastery, presents the historical protestant school and shows the impacts of taking care of historic monuments. One of its chapters describes a systematic step-by-step tour of the whole monastery complex.
