According to the legend there was a cave in which St. Petka tried to hide from infidels that were persectuing her. In that cave are still preserved foot and hand prints and a stone bread. The saint hid in the cave, lit a fire and baked a load of bread. At that time though her persecutors found the cave and got in. Luckily the smoke from the fire showed St. Petka that there is another way out of the cave and she ran away. When the persecutors reached out to the loaf of bread it turned into stone.
This cave is now a stone church “St. Petka”. Inside it there are two steps cut out in the stone – remaining from the time when she managed to escape her persecutors. Inside the stone church stays also the stone bread – a large stone disk with a hole in the center.
