One of the nation’s first mixed-use developments, Crown Center was an experiment in post-World War II urban design developed by Hallmark which now brings in more than 5 million visitors each year. The 85-acre Crown Center is frequently referred to as a “city within a city.” Crown Center Square houses live music performances, the city’s only public outdoor ice skating rink and is home to the LEGOLAND Discovery Center, SEA LIFE Kansas City Aquarium and Kaleidoscope. There are several mid to upscale stores, and visitors can stay at the Sheraton Crown Center or the Westin Crown Center. The Coterie Theater, one of Crown Center’s three live entertainment venues, was recognized by Time as one of the top five children’s theatres in the country. Crown Center’s WeekEnder series features a live local music show followed by a crowd favorite film on a huge outdoor screen in Crown Center Square on Fridays in July. The district is a short walk from Liberty Memorial (which features a world-class World War One museum). Visitors can connect to Union Station and the rest of Crown Center via a skywalk called the Link.
