Dubai has four human-made islands- The Palm Jumeirah, the Palm Jebel Ali, Deira Island and The Worlds. The Palm Jumeirah is one of the largest human-made islands in the world! This island is designed in the shape of a palm tree with fronds and branches spreading out. It is more like a mini-city. The Palm Jumeirah has many hotels, homes and is even equipped with a monorail.
