Archaeologists in Gliwice, southern Poland have discovered a burial ground where the dead were laid to rest in accordance with practices for alleged vampires. Four skeletons were found at the site, where mandatory digs were being carried out prior to the construction of a ring road.
In each case, the deceased had been buried with the head between the legs. According to folk beliefs, this prevented a possible vampire from finding his or her way back to the land of the living.
“It’s very difficult to tell when these burials were carried out,” archaeologist Dr. Jacek Pierzak told the Dziennik Zachodni newspaper. However, it is believed that they took place in the early modern period.
The last recorded instance of a vampire burial within current Polish borders was in Stare Mierzwice, Masovia, in 1914. A corpse was dug up in the village [with] its head cut off and placed between the legs.
