The Castle at 501 Prospect is Beloit's newest entertainment and performing arts venue.
Beloit's newest entertainment and banquet venue makes its home in one of Beloit's oldest buildings. The Castle was originally built in 1906, and enjoys Landmark status in the city's Near East Side Historic District. Gothic architecture and stained glass provide the atmosphere to a building that has been re-purposed for the performing arts, event hosting and banquets. In addition to concerts by the BJSO, various local and touring artists perform in an acoustically stunning amphitheater, complete with a towering pipe organ. The King's Court Players are the resident theater troupe that provide live entertainment during interactive dinner theater performances. Guests can browse through original artwork or enjoy a cocktail in the Bell tower Lounge, overlooking the historically preserved theater. The Castle is available for weddings, banquets and corporate events and provides complete catering services for groups up to 400.
