This skeleton, discovered at the site of the ancient Thracian temple of Perperikon, southeast of the Bulgarian capital, Sofia, has an iron rod through its chest where its heart should be.
The graves were found by archaeologist Nikolai Ovcharov. He says that in the Middle Ages the practice of pinning an iron bar through the chest was believed to stop the dead from becoming vampires.
These are the sixth and seventh "vampire" graves discovered in the country in the past two years.
Ovcharov told The Telegraph: "We have no doubts that once again we’re seeing an anti-vampire ritual being carried out."
"Often they were applied to people who had died in unusual circumstances – such as suicide," Ovcharov told the paper.
