One of four local daughters, Gyusha, spotted an invading army and the girls were able to run and give their fortress warning. However, after a week of siege, traitors opened the gate and let the army of the enemy in. The four sisters were captured but managed to escape and tried to flee to a local monastery. However, one of the invading army, Omur, pursued them and with a vicious blow, severed Gyusha’s head. The miracle happened and she turned in to a beautiful stone mushroom. Omur killed the remaining three who then, successively, turned to stone as well.
The village of Beli Plast in Bulgaria is home to some strange looking giants that look like stone mushrooms. They are limestone boulders which have been weathered away over the millennia, but the locals have a much more supernatural explanation.
