I got asked to contribute a few more stories from my country, so here's one from the town I'm from.
The city of Norwich is beautiful and part of its charm is that a lot of buildings from the 1600's still exist, if only for show or as museums. But in one of these buildings something else from that time still remains.
In england in 1665 we suffered the great plague, and hit all over the country, including Norwich. Sadly many died, painfully, often wiping out entire families. The city coped by building what we're known as plague pits, where the bodies of the infected we buried in mass graves to try to kill the infection. Another option was to seal infected families within their homes if all inside were dead. Once this had been done, a large red cross was painted on the door, signaling to others not to enter. One such house was sealed as such, and far as the city was concerned with that was that. However, when, after a period of time, the house was opened up again to clear the corpses they found something they hadn't expected. They were horrified to learn that not all inside had been dead. Most of the family inside bore the marks of plague; sores and rose like bruises, but they also bore teeth marks on their limbs, human teeth marks. It turns out that the daughter had unwittingly been trapped inside with her family, and had had to feast on her relatives flesh to try and survive. Sadly she had choked on a piece of flesh and died. It is said that she still haunts that house and the alleyways surrounding it. She is known as they Grey girl as that is how she always appears, mournful and grey but harmless...
