The International Riverfront encompasses a cruise ship passenger terminal and dock, a marina, a multitude of parks, restaurants, retail shops, skyscrapers, and high rise residential areas along with Cobo Convention/Exhibition Center and Joe Louis Arena. The Marriott at the Renaissance Center and the Robert's Riverwalk Hotel are also situated along the International Riverfront. Private companies and foundations together with the city, state, and federal government have contributed several hundred million dollars toward the riverfront development. Key public spaces in the International Riverfront, such as the RiverWalk, Dequindre Cut Greenway and Trail, William G. Milliken State Park and Harbor, and a cruise ship passenger terminal and dock at Hart Plaza complement the architecture of the area.
