The cave of Kryonerida is located at an altitude of 230 meters in the area of Lagos. The cave has no particular petrological value, but a particularly significant historical value. According to history, in 1821 here, the villagers of Vafes were murdered in a horrible way.
The cave consists of four rooms and its entrance is 1.80 meters wide and 1.50 meters high. The first room is the largest, while the second is the place where the bones, those who lost their lives from the Ottomans. In the last room, there is the spring of water, from which the cave was named.
130 civilians in the village of Vafes trying to hide, found refuge in the cave. It is said that the Ottomans heard the cry of a baby and discovered the civilians. However, the entrance to the cave was very small and so they decided to light a fire. The besiegers died of suffocation, but only seven survived.
At the entrance of the cave, there is an iconostasis in their honor and is honored every August.
Almost opposite Kryonerida is the chapel of St. John in a recess in the mountain.
In the Lagos Gorge, there is also the Kalamato Cave, which consists of many chambers, precipices, stalagmites, and stalactites. The cave is accessible only by experienced speleologists.
