The ancient city of Constantine is located in modern-day Algeria. Its ancient name was Cirta, and it served as the capital of the Numidian kingdom in North Africa before becoming an important Roman city.
The city was renamed Constantina in the 4th century CE in honor of the Roman emperor Constantine the Great. Over time, that name evolved into Constantine. The city stands in northeastern Algeria, dramatically built around the deep Rhumel Gorge.
A common mix-up is calling Constantine a Phoenician city. Phoenicians established important settlements across North Africa, but Cirta was chiefly associated with the Numidians and later Rome. Algeria is nevertheless the clear modern country answer.
Constantine is one of Algeria’s major historic cities and is often nicknamed the “City of Bridges” because of its spectacular bridges spanning the gorge.
