The small chapel of Agia Varvara is located outside Argostoli, in a cave under the main provincial road. The area was originally called Agios Barbaros. According to tradition, in 1912 a small refugee child fell from the road down into the ravine, but landed on the ground without even suffering the slightest injury! The child himself is said to have stated that he was helped to get down by a woman in white clothes.
Since that incident, villagers passing by, kept seeing a flame that was constantly burning inside the cave all year round. Years later, some built the courage to investigate the mysterious flame, so they went down, inside the cave, only to discover the icon of Agia Varbara. Convinced that it was a miraculous icon, the villagers took it to Argostoli, where an epidemic had burst out and was ravaging the people. The epidemic stopped. Back to the village, a chapel was built inside the cave to honor Agia Varvara and the miraculous icon was placed in it. The chapel can be seen today, from the bridge connecting the road. After 1953, the icon disappeared, many believe it was stolen. Every year on the 4th of December, the locals celebrate the salvation from the epidemic at the chapel.
