Because of the professional opinion that the region of Aegean Sea is an inexhaustible palaeontological treasure there is a Museum of Natural History in the village of Mitilinii since 1992. Fossils of mammals that had been living 8-10 million years ago, some of which unique, are the real proofs of the natural history of the European continent. The picturesque gulfs with calm as well as lively beaches, the greenery that the several fires could not devour and the glassy sea water fascinate with their natural beauty.
