Castell Castle

Switzerland, Switzerland

---

Castell Castle is a historic manor-turned-castle in Tägerwilen, Canton of Thurgau, Switzerland, overlooking the region from a ridge near Lake Constance, with nearby ruins of a 12th-century predecessor that was once among the largest medieval fortifications in the area.

Built in 1585 by Junker Konrad, Vogt of Wartenfels, as a late Renaissance manor house replacing a farmhouse, it passed through noble families like the Segesser von Brunegg, Zollikofer, and von Scherer, who remodeled it in 1725 and later in Neo-Renaissance style between 1878 and 1894 with frescoes depicting its history and a replica Moorish hall.

Recognized as a Swiss heritage site of national significance, the private 160-hectare estate supports agriculture and forestry, remains closed to the public but visible from roads, with its pond, woods, and ancient ruins accessible.
