Visualize the ancient city of Babylon at its height during the reign of Nebuchadnezzar II, around 600 BCE. The city is sprawling with large, rectangular brick buildings, majestic palaces, and towering ziggurats. In the center, depict the grand Ishtar Gate with its vibrant blue-glazed bricks adorned with golden reliefs of dragons and bulls. The processional street leads from the gate into the heart of the city, flanked by statues and lush gardens. The mighty Hanging Gardens of Babylon rise in the background, with cascading greenery and terraces. The scene should capture the hustle and bustle of Babylonian life, with traders, nobles, and priests in traditional robes. Surround the city with the Euphrates River and massive city walls, under a clear sky with the sun casting a warm glow over this magnificent ancient metropolis.
