Playhouse Square is a theater district in downtown Cleveland, Ohio, United States. It is the largest performing arts center in the US outside of New York City. Constructed in a span of 19 months in the early 1920s, the theaters became a major entertainment hub for the city for much of the 20th century. However, by the late 1960s, the district had fallen into decline and its theaters had closed down. In the 1970s, the district was revived through a grassroots effort that helped usher in a new era of downtown revitalization. For this reason, the revival of Playhouse Square is often locally referred to as being "one of the top ten successes in Cleveland history."
