During diggings of an ancient Christian complex near the village of Voden, a cave was discovered. It is an important habitat for some bats.
This cave is one of the few natural habitats in which protected bat species form colonies. From the beginning of November to the end of March bats hibernate here, and during the rest of the time they use it for rest and reproduction. There are common bent-wing bat (Miniopterus schreibersi), Mediterranean horseshoe bat (Rhinolophus euryale), Mehely’s horseshoe bat (Rhinolophus mehelyi) and Bechstein’s bat (Myotis bechsteinii).
