Castle Mainberg - Historic Jewel Overlooking the Main River

Castle Mainberg is a remarkable historical property perched above the village of the same name, nestled in the municipality of Schonungen in the Schweinfurt district of Saxony-Anhalt. Surrounded by woods and a vineyard, the castle boasts stunning views over the Main River. It is located just 3 kilometers from the Schweinfurt city limits, with convenient city bus access and only a 10-minute drive to the nearest motorway. 

Once owned by the prominent Schweinfurt industrialist family Sachs, the property underwent extensive renovations in the historic late-Romantic style. These renovations continue to define the castle’s stately interior, with each room showcasing its own unique character. 

Castle Mainberg is a protected historic monument of extraordinary cultural significance. Its rooms were individually designed by Munich-based architect Franz Rank at the request of Ernst Sachs, reflecting a one-of-a-kind architectural vision. 

In recent decades, the castle has been used for gastronomy, private events, and residential purposes.

History and Cultural Significance

Castle Mainberg, located just outside Schweinfurt and overlooking the Main Valley, holds a richly layered history that spans from the High Middle Ages into the 20th century. Few former noble residences in Franconia exhibit such a wealth of artistic and literary attention: artists like Matthäus Merian, Ludwig Richter, and Hans Thoma captured the castle in paintings and drawings, while author Ludwig Bechstein once described it as a “marvelous fairy-tale castle.”

The property was first mentioned in 1245 and acquired its current form with three stepped gables during the medieval period. From 1305 to 1542, it belonged to the Counts of Henneberg. Following that, ownership changed hands several times. Ernst Sachs acquired the property in 1915, followed by his son Willy Sachs until 1954. Gunther Sachs, his grandson, was born at the castle. Between 1954 and 1960, Wilhelm Heger owned it, followed by the city of Schweinfurt from 1961 to 1982. In 1983, Gerhard Eichhorn purchased the property and used it for events. Today, the castle is privately owned.
