The Entire Story Constantine the Great refounded the ancient Greek city of Byzantium as Constantinople and made it the new capital of the empire. On the 8th of November 324 Constantine formally laid out the boundaries of his new city, roughly quadrupling its territory. By 328 the new walls were completed, and on the 11th of May 330 the new city was formally dedicated. This coin was minted to commemorate this grand occasion.
