5Babylon – Iraq
Babylon, one of the most famous cities of the ancient world, was the capital of the Babylonian Empire, which reached its height under King Nebuchadnezzar II in the 6th century BCE. The city is legendary for its grand walls, the Ishtar Gate, and the Hanging Gardens—one of the Seven Wonders of the Ancient World (though their existence is debated). Babylon was eventually abandoned due to invasions and political instability, and its ruins now lie near modern-day Baghdad. Excavations have revealed the grandeur of its temples, palaces, and infrastructure, offering a glimpse into one of history’s most influential civilizations.
