Detroit International Riverfront in the context of "Riverwalk Hotel Detroit"

The Renaissance Center, commonly known as the RenCen, is a complex of seven connected skyscrapers in downtown Detroit, Michigan, United States. Located on the Detroit International Riverfront, the RenCen is owned and used by General Motors as its world headquarters. The complex includes a 73-story Marriott hotel at its center, surrounded by four 39-story office towers, connected by a large square podium containing public spaces, a conference center, retail stores, restaurants, and a company showroom.

Developed as an urban renewal project in the 1970s, the Renaissance Center was envisioned as a "city-within-a-city," and was meant to anchor a wider redevelopment of the then-declining city of Detroit. The project was developed and funded by a consortium led by the Ford Motor Company, and John Portman served as its principal architect. The five original towers were built in the Modern architectural style and completed in 1977, with two matching towers added later in 1981.

Detroit is the largest city in the U.S state of Michigan, with a metropolitan area population of 4.4 million as of 2025. Detroit is home to 39 buildings taller than 300 feet (91 m), nine of which are skyscrapers with a height of 492 ft (150 m) or more. Detroit has one of the largest skylines in the Midwestern United States, with the third most skyscrapers above 492 ft (150 m) in the region, after Chicago and Minneapolis. The tallest skyscraper in Detroit is the 70-story Detroit Marriott at the Renaissance Center, which rises 727 ft (221.5 m) along the Detroit International Riverfront in the city's downtown. The skyscraper is one of seven towers in the Renaissance Center complex, which has served as the headquarters of General Motors since 1996, reflecting the city's role in the automotive industry. The Detroit Marriott is the tallest building in Michigan and was the tallest hotel building in the world upon completion in 1977; it is currently the third tallest in the Western Hemisphere.

Detroit's history of skyscrapers began in 1889, with completion of the historic 10-story Hammond Building—considered the city's first steel-framed skyscraper. Detroit grew to become the fourth-largest city in the United States by the 1920s, and witnessed a massive building boom during the Roaring Twenties. Many ornate skyscrapers were build during this period, including the Penobscot, Guardian, Fisher, Buhl, and David Stott buildings. This resulted in Detroit having one of the world's largest skylines at the time outside of New York City and Chicago. By 1930, the city had thirteen 300-foot buildings. The Great Depression brought an end to the boom.
