The heart of the Millennium City, Downtown is the home of the breathtaking architectural wonders known as the Renaissance Center. The “Ren Cen” skyscrapers may be the primary reason Millennium City got its nickname, “The City of the Future,” but in Downtown there are several poignant reminders of the past. Millennium City was built upon the ashes of Detroit, a city reduced to ruin after a savage attack by Dr. Destroyer. Both Memorial Park and the Battle for Detroit Museum pay remembrance to the citizens and superheroes who died during the terrible assault. The Hall of Heroes, meanwhile, honors the heroes of the present, who risk their lives on a daily basis to ensure Millennium City is safe and secure.
