Chalcis (/ˈkælsɪs/;^[4] Ancient Greek & Katharevousa: Χαλκίς, romanized: Chalkís), also called Chalkida or Halkida (Modern Greek: Χαλκίδα, pronounced [xalˈciða]), is the chief city of the island of Euboea or Evia in Greece, situated on the Euripus Strait at its narrowest point. The name is preserved from antiquity and is derived from the Greek χαλκός (copper, bronze), though there is no trace of any mines in the area.^[5][6] In the Late Middle Ages, it was known as Negropont(e), an Italian name that has also been applied to the entire island of Euboea.
