Persepolis was the ancient city that served as the center of the Persian Empire. Founded by Darius the Great in the 6th century BC, Persepolis was strategically located in present-day Iran and represented the grandeur and sophistication of the Achaemenid Empire. The city was known for its impressive palaces, monumental staircases, and richly detailed relief sculptures, showcasing the power and wealth of Persia. Persepolis served not only as a ceremonial capital but also as a symbol of the empire’s cultural and political strength. Today, its ruins are a UNESCO World Heritage site, reflecting the enduring legacy of the Persian civilization.
