Palm Jumeirah is a man-made island in the shape of a palm tree, located in Dubai. It is one of the most iconic architectural feats in the world, built by Nakheel Properties. The island is comprised of a trunk, 16 fronds, and a crescent-shaped breakwater. It was developed using land reclamation techniques and took over six years to complete, transforming Dubai's coastline and becoming a symbol of luxury and innovation.
