During archaeological excavations in 2012 the remains of a skeleton pierced with an iron bar in the heart were found. It is believed that those are the remains of the local nobleman Krivich (or Krivitsa), ruler of the fortress of Sozopol (castrofilax). Believed to be a very cruel person, the locals made sure that he would not come back to haunt the city after his death by piercing him with an iron bar in the chest.
