Chalcolithic, also known as the Copper Age, is a period of human history that predates the Bronze Age. It is characterized by the use of copper and other metals, in addition to stone, in the manufacture of tools and weapons.
Chalcolithic sites are places where artifacts and other evidence of Chalcolithic culture have been found. These sites can be found all over the world, and they provide important insights into the technological, social, and economic developments of this period.
Some of the most well-known Chalcolithic sites include Tel Dan in Israel, Çatalhöyük in Turkey, and Varna Necropolis in Bulgaria.
