Chalcis (/ˈkælsᵻs/; Ancient Greek & Katharevousa: Χαλκίς, Chalkís) or Chalkida (Modern Greek:Χαλκίδα, [xalˈciða]) is the chief town of the island of Euboea 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. In the late Middle Ages, it was known as Negropont (Italian: Negroponte, "black bridge"), a name that was applied to the entire island of Euboea as well. Its people are known in English as Chalcidians.
