The capital city of the ancient Persian Empire was Persepolis. Founded by Darius I in the 6th century BCE, it served as a ceremonial capital and was a showcase of the empire's grandeur. The city was adorned with magnificent palaces, impressive monuments, and intricate reliefs that depicted the empire's diverse cultures. Persepolis was strategically located, facilitating trade and cultural exchange across the vast territories of Persia. Its ruins, which remain in present-day Iran, offer valuable insights into the architectural and artistic achievements of the Achaemenid Empire, as well as its administrative and ceremonial practices.
