Every year on August 15 the Assumption of the Holy Mother of God is celebrated at the chapel on Kato Koufonisi.

In the morning the fishing boats from Pano Koufonisi take the devout to Kato Koufonisi to hear Mass in the Virgin’s chapel.
It is the only day in the year when the little ferry boat Skopelitis, which serves the Mikres Cyclades line, deviates from its normal course to call at Kato Koufonisi, at the jetty near the chapel.
After Mass the congregation are offered various delicacies that the inhabitants have prepared.

Later the fishing boats take people back to Pano Koufonisi, indulging in a playful race amongst themselves on the way.

On Pano Koufonisi the celebration continues.
