Created out of rock and sea sand, the islands are an extraordinary man-made creation. The islands consist of a five kilometre long ‘trunk’ and 17 ‘palm fronds,’ protected by a half-moon shaped wave break. Work on the project began in 2001. The creation of the palm islands has resulted in ground conditions of sand coral and limestone. Contractor Al Naboodah Engineering Services chose HDD and microtunnelling to install pipes and services between the ‘fronds’.
