The Renaissance Center, commonly known as the RenCen, is a landmark mixed-use building complex in downtown Detroit, Michigan, United States. Located on the Detroit International Riverfront, the complex consists of seven connected towers, including a 74-story Marriott hotel, and the tallest building in Michigan at its center. Four shorter office skyscrapers surround the hotel, with two shorter, auxiliary office towers to the east. The towers are connected by a large square podium containing extensive public spaces, a conference center, and retail stores.
