| It lies close to the marble quarries near the Longoz Village of the Igneada District. Abundant number of bats (Rhinolophus hipposideros; Rhinolophus euryale) were seen. Mermer Cave is a fossil cave near the Marble quarries north of Sivriler Village in Demirköy. The cave is formed inside the Mesozoic marble layers in Mesozoic metamorphic and intrusive rocks of Strandja Massif. Mermer Cave is 36 m deep and 96 m in length. The cave ends in a very narrow passage, which most probably connects to the river basin. About 20 m from the entrance, there is a 15 m deep pit with low levels of oxygen. Precaution must be taken before going down to this gallery. Rhinolophus euryale colony (approximately 350 individuals) hibernate at the bottom of Mermer Cave. This is the most important biospeleological feature of the Cave. There is also a small nursery colony of Rhinolophus blasii during the summer period. |
