The island of Polyaigos is the largest uninhabited island of the Aegean Sea. It is one of the most beautiful destinations for lovers of sailing with numerous pristine beaches with emerald waters. As the island is uninhabited, there are not many sights of interest except the sceneries of nature. The Lighthouse of Polyaigos lies on Cape Maskoula on the east side of the island. The remnants of the Church of Virgin Mary are located on the northwest side of Polyaigos. Today, the island is uninhabited and it has been declared as an area of outstanding beauty and an important natural place of the Mediterranean Monk Seal Monachus-Monachus from the European Network of Natura 2000!
