History+
The first mention of the locality Faulenrost dates back to 1275, when Knight Henning von Rostock was enfeoffed with the property by Prince Nikolaus von Werle-Güstrow. Construction of the castle began in 1760 under Knight Claus Ludwig Hahn, who intended to develop Faulenrost into his summer residence. After his death, his successor, the astronomer Friedrich II von Hahn, completed the building and laid out gardens. In 1933, the estate was sold to a Berlin settlement company and later acquired by the political municipality. It served various purposes, including as a camp for female labor service, accommodation for NS organizations, and even as a church. After World War II, it housed war refugees, a kindergarten, and a school, before progressively falling into disrepair and being destroyed by fire in 1969.
