A fellow tourist summed it up perfect (excerpt from German Eagle)
The Cistercian monastery, origin of the town, was founded in 1149 by Berthold III von Eberstein and his wife Uta. It became economically successful, in the 14th and 15th century it prospered. However, the end came soon: In 1525 farmers plundered it, as a result of the Reformation it was closed down in 1534 and turned into a school. In the 30-years war the Swedish troops burned it almost completely down.
So, not much is left of the monastery buildings. The still existing choir of the former monastery church was incorporated in the construction of the ev. parish church. Best preserved is the so called “paradise”, the entrance hall of the former monastery church (pics 1 – 3). The “paradise” was built about the year 1200, in 1462 the beautiful gable in Gothic style was added. Portal and windows are still in Romanesque style. Inside are some old epitaphs.
The monastery grounds are still the heart of Bad Herrenalb. But nowadays you find things like the Kneipp bath (pic 4) and a monument (pic 5) on the grounds. Relics from the Cistercian era are also the parsonage and the adjoining house, some remains of the walls and a barn.
Access is free, always open. For the ev. church see separate tip.
