The “Streets of Monaco” is the first of our billion-dollar yachts.

When completed, the 509-foot mega yacht Streets of Monaco will be among the world’s most impressive and expensive vessels, boasting tiny replicas of some of Monaco and Monte Carlo’s most famous monuments.

When completed, the superyacht will feature a mini-submarine, a helipad, seven guest cabins, a waterfall, and a restaurant with a spectacular view of the ocean floor below.
