Schloss Mammern

Mammern, Switzerland

---

Schloss Mammern is a historic castle in the municipality of Mammern, Canton of Thurgau, Switzerland, on the shores of Lake Constance, originally documented in the early 13th century and rebuilt in 1621 by the von Roll brothers as a Renaissance-style residence.

It later came under Rheinau Abbey's control in 1687 before becoming a sanatorium and then, since 1889, a renowned private rehabilitation clinic owned by the Ullmann family across four generations, specializing in cardiovascular, musculoskeletal, oncological, and pulmonary recovery with modern facilities amid its preserved architecture.

Recognized as a Swiss heritage site of national significance, it features luxurious patient suites, gourmet dining, and healing gardens overlooking the lake, blending medical excellence with historic charm.
