Schloss Zinneberg, Heritage castle in Glonn, Germany

Schloss Zinneberg stands on a projecting spur of the Zinneberg hill at the eastern edge of Glonn, largely hidden behind dense trees. The multi-wing complex, rebuilt after a fire in 1632, includes a long two-storey building with a hipped roof and three-storey central risalit, a late-medieval core section, a former brewery with a gate passage, and an orangery with a glass front and roof balustrade built by Friedrich von Thiersch in 1904.

The castle was first documented in 1332 as a noble residence and underwent major changes under owners including the Fugger family. Countess Maria Leopoldine also contributed to its transformation before it took on its current purpose.

The name Zinneberg comes from the hill spur on which the castle stands. Since 1927 the property has belonged to the Sisters of the Good Shepherd, who ran an education home here and still run a youth welfare facility for girls from difficult circumstances, plus a kindergarten. A legend holds that a secret passage once linked the castle to the village.

The complex stands at the eastern edge of Glonn on the projecting spur of the Zinneberg, screened by dense trees and visible only in outline from outside. It is run by the Sisters of the Good Shepherd as a youth welfare institution for girls and also houses a kindergarten, so the grounds are not a public visitor site. Since 2022 a new Mittelschule has been under construction on the meadow beside the sports field, because the former Orangerie needed urgent renovation.

A legend holds that a secret passage once linked the castle to the village, allowing residents to flee during the Thirty Years' War. The castle was burned down in 1632, and this tale has survived ever since.
