The National Marine Park of Alonnisos Northern Sporades (Greek: Εθνικό Θαλάσσιο Πάρκο Αλοννήσου Βορείων Σποράδων, ΕΘΠΑΒΣ) was founded by Presidential Decree on May 16, 1992. It was the first of its kind in Greece, and is currently the largest marine protected area in Europe (approximately 2.260 km²). Besides the sea area, the park includes the island of Alonnisos, six smaller islands (Peristera, Kyra Panagia, Gioura, Psathoura, Piperi and Skantzoura), as well as 22 uninhabited islets and rocky outcrops. It is located in the region of the Northern Sporades Islands, in the northern Aegean Sea.
