The "mysterious" tomb of Elizabeth Báthory https://en.wikipedia.org/wiki/Elizabeth_B%C3%A1thory : under the church or in the retaining wall...In 1938, the parish priest together with another group of people found many coffins with young women's bodies in the skep - evidently the victims.... Báthory is a blood relative of Vlad III. https://en.wikipedia.org/wiki/Vlad_the_Impaler
After this discovery of a huge number of coffins, the search was quickly and strictly stopped, with the sanctification of the authorities. It's more than astonishing that no more detailed reports have survived from the research carried out. BUT, local people know about the secret rooms, underground corridors and other monstrosities associated with this place...in many places in Czechia/Bohemia, the transmission of information transmitted by the heart - from generation to generation.

Werewolves and vampires, old families.
Eleonore von Schwarzenberg https://de.wikipedia.org/wiki/Eleonore_von_Schwarzenberg
She not sleep at night and turned the castle into an alchemical laboratory and preferred mother's milk from wolves. Her tomb is more than interesting... in Český Krumlov/Bohemia. Her husband was shot by the emperor while hunting (just in time for the full moon?.). The area of Central Europe has a very long history about vampires and werewolves. Does anyone really still think that when the data can be preserved for more than a few millennia and gradually the truth of the claim is proven that it is a fabrication?
It will be difficult to accept the truth, especially for those who do not have the divine spark within them.
In the same way, the family of Rosenbergs is associated not only with vampires, but above all with werewolves. And many other black noble families which have one thing in common - a kinship with the families from period of the first Babylon.
