Constantine (Arabic: قسنطينة, Qusanṭīnah, also spelled Qacentina or Kasantina, Arabic: Blad el-Hawa) is the capital of Constantine Province in Northeast Algeria.
During Roman times it was called Cirta and was renamed "Constantina" in honor of emperor Constantine the Great. It was the capital of the same-named French département until 1962. Slightly inland, it is about 80 kilometers (50 miles) from the Mediterranean coast, on the banks of the Rhumel river. Regarded as the capital of eastern Algeria and the centre of its region, Constantine has a population of 448,374 (1,000,000 with the agglomeration), making it the third largest city in the country after Algiers and Oran. There are museums and important historical sites around the city (one of the most beautiful is the Palais du Bey, in the Casbah). It is often referred to as the "City of Bridges" due to the numerous picturesque bridges connecting the mountains the city is built on.
