Almost one third of Serifos, from the south and southwest shores to the slopes of Panagia and Galani villages, northeast of the Troulos top, has become a “Natura 2000” site (Natura 2000 is a European network for the protection of the Mediterranean biodiversity, the natural habitats and wildlife of the region).
