Agia Marina Church, nestled in the picturesque village of Mylopotamos on the island of Kythira, is a distinctive example of ecclesiastical architecture. Uniquely, the church is built into the side of a rocky mountain, creating a harmonious blend with its natural surroundings.

The church's interior features traditional Orthodox design elements, including a modest iconostasis and simple yet reverent decorations. Its serene atmosphere offers visitors a place for contemplation and spiritual reflection.The church celebrates its feast day on July 17th, honoring Saint Marina.
