A vampire burial or anti-vampire burial is a burial performed in a way which was believed to prevent the deceased from reviving in the form of a vampire or to prevent an "actual" vampire from revenance.
[1][2][3] By an association, the term "vampire burial" may also refer to burials apparently performed with rituals associated with beliefs that the buried may arise from the dead or evil spirits may come out of the grave, etc., and these rituals were intended to prevent this from happening.
An example of this is believed to be the case of mid-5th century "Children's Necropolis" of Lugnano in Teverina, Italy.
[4] Vampire burials had other byproducts, whether intentional or not, that as well counteracted various outside forces that could be imparted onto a deceased body, such as protection from scavengers, erosion damage, and having the body resurface due to storms.
[5] Archeologists uncovered a number of burials believed to be of this type.
