Caesarea was actually the name of three separate cities: one in Palestine, one in Cappadocia (Asia Minor), and one in Mauretania, present-day Algeria. The first city, Caesarea Maritima, was built by Herod around 25 BCE and, like the other two cities, was named for Roman emperor Augustus (r. 27 BCE to 14 CE). It served as an administrative capital for the province, and in the 1st century CE, Emperor Vespasian (r. 69-79 CE) made it a colonia. The city would later become the capital of Judea.
