Chios is notable for its exports of mastic gum and its nickname is The mastic island. In the south of the island are the seven Mastichochoria, literally Mastic Villages, among which Mesta and Pyrgi. The villages, built between the 14th and 16th centuries, have a carefully designed layout with fortified gates and narrow streets to protect against the frequent raids by pirates. The 11th- century monastery of Nea Moni, a UNESCO World Heritage Site, is another important tourist attraction.
Beyond sightseeing, Chios has many beaches, such as Agia Fotia, Karfas and Mavra Volia with black pebble, each with its own character and good food in all of its towns and villages.
