Introduction to the Hanging Gardens of Babylon: The Hanging Gardens of Babylon were built between 604 and 562 BC. It is located 56 miles south of Baghdad, the capital of the Republic of Iraq. It was built by King Nebuchadnezzar II of ancient Babylon for his favorite queen. Because the queen was a Mede, the king ordered craftsmen to build a layered terraced garden in his palace according to the scenery of the Mede mountainous area. It was planted with exotic flowers and plants, and a quiet garden was opened in the garden. There is a mountain trail with gurgling water beside it. The craftsmen also built a tower in the center of the garden, standing in the air. Because the garden is higher than the palace wall, it feels like the entire imperial garden is hanging in the air, so it is called "hanging garden" or "hanging garden". The ancient Greeks who saw it at that time called it a wonder of the world.
