Cincinnati is more interesting than most American cities of its size. The Cincinnati Art Museum in Eden Park is free and has a strong collection spanning 5,000 years. The Cincinnati Museum Center at Union Terminal — a stunning Art Deco train station — houses natural history, history, and science museums under one spectacular roof. The Cincinnati Zoo is one of the best in the Midwest. Over the Rhine, just north of downtown, has the country's largest intact urban historic district and has transformed into a lively neighbourhood over the last decade.
