A few kilometers to the northeast of Frenaros village there is a chapel dedicated to Agia Marina.
Built at the end of the 15th century, the chapel can only accomodate 50 to 100 persons.
Though its exterior is built with stone inside it looks very simple. On the walls there are signs of old frescos.
On july 17 nameday of Agia Marina big crows gather at the chapel for the annual village fair held there.
