Little Caesars Arena is a multi-purpose arena in Midtown Detroit. Construction began on April 24, 2015 following a formal groundbreaking ceremony on September 25, 2014. Opened on September 5, 2017, the arena, which cost $862.9 million to construct, succeeded both Joe Louis Arena and The Palace of Auburn Hills as the homes of the Detroit Red Wings of the National Hockey League (NHL) and the Detroit Pistons of the National Basketball Association (NBA), respectively.The arena features a unique, glass-roofed concourse connecting it to offices and shops surrounding it. It will anchor a new $2.1 billion 650,000sqft sports and entertainment district in and around downtown Detroit that will include mixed-use neighborhoods with new residential and retail outlets located around the Cass Corridor, Ford Field and Comerica Park.DesignLittle Caesars Arena was designed by HOK, and features a unique "deconstructed" layout. Buildings housing retail outlets, the arena's box office, and the offices of the Red Wings are built outside the arena, but a glass roof is erected between the buildings and the arena itself. The roof forms an indoor "street" that serves as the arena's concourse. The concourse will remain open year-round, even if an event is not occurring inside the arena, allowing it to also be used as a venue of its own. There is also an outdoor plaza with a large video display.
