Description
Castle in St. Gallen – Representative, completely renovated castle with lake and distant view
In the area where the foothills of the Pre-Alps reach the shore of Lake Constance, the castle majestically towers over the picturesque landscape. From "Collection Nobilis Estate No. 4", one can enjoy a breathtaking view over the Swiss Lake Constance shore and the wide, glittering water surface of the Obersee. Within the protective walls, an outdoor pool invites relaxation on the sunny slope.
Rudolf I. von Sulzberg, originating from the Allgäu region, began constructing the powerful bergfried around 1230. At the end of the 14th century, a palas was added – the foundation for the current residential tract. In 1474, the castle was acquired by the Ravensburg merchant family Mötteli and converted into a residential castle. From 1578 to 1857, the property was owned by the Bündner noble family von Salis.
"Collection Nobilis Estate No. 4" houses six residential units, one of which is located in the separately situated servant's house. Apart from being used as a spacious residential and family residence, the castle is also perfectly suited as a company headquarters. Due to space constraints, only the approximately 600 m2 large master apartment of the castle lady/castle lord can be described here.
