Mastichochoria refers to the traditional villages on the Greek island of Chios, known for their unique production of mastic, a resin obtained from the mastic tree. These villages, including Mesta and Pyrgi, are characterized by their medieval architecture and narrow, winding streets. The cultivation and harvesting of mastic have been a significant part of the local economy and culture for centuries. The mastic tree, scientifically known as Pistacia lentiscus, thrives in the region's climate and soil. The process of collecting mastic involves making small cuts in the tree's bark, allowing the resin to ooze out and harden. This resin is used in various products, including food, cosmetics, and traditional medicine, making Mastichochoria an important cultural and economic area on Chios.
