The Hanging Gardens of Babylon was built in 800 BC on the banks of the Euphrates River in Iraq. Emperor Nebuchadnezzar built it on the inspiration of the empress. At first a huge foundation was built , the area of which was 600 square feet. The foundation was laid on the spacious roof of the then emperor's khas shrine. After laying the foundation, it stood 60 feet above the ground. The world's largest and most wonderful flower garden was built on this foundation. The garden was created by 4,000 workers working day and night. 1050 gardeners were engaged in gardening. 5 to 6 thousand types of flower saplings were planted in this hanging garden. Water was pumped from the river to the high steps of the garden at a height of 60 feet with the help of a thick spiral tube. This beautiful park was completely destroyed in 514 AD in a bloody battle with the neighboring Persian Empire.
