Sheikh Mohammed bin Rashid Al Maktoum made the surprise announcement today about the Dubai Harbor.
The harbour is planned to be over 20 million square feet (1.86 million square meters) and will include a cruise ship port and terminal. The project also will include a 135-metre tall lighthouse.
Meraas, a developer backed by Sheikh Mohammed, will build the project between Dubai's Jumeirah Beach Residence neighborhood and the man-made Palm Jumeirah archipelago.
Authorities offered no cost estimates for the project.
