Founded in 1928, Berkshire Theatre Festival is one of the oldest professional regional theatres in the United States and the longest-running cultural organization in the Berkshires. Now under the leadership of Artistic Director and CEO Kate Maguire, BTF presents theatre that matters-world premieres, contemporary works, and classics that speak to who we are in our world today. The Main Stage (408 seats), cataloged by the National Register of Historic Places, was originally designed and built by Stanford White as the Stockbridge Casino in 1888. The mission of BTF's second stage, the inimate Unicorn Theatre (122 seats) is to provide a home for emerging artists and new theatrical ideas . BTF's education program, BTF PLAYS!, reaches over 10,000 children annually through school residencies, touring performances, and summer performance training and writing programs. During the summer months BTF opens its doors to over 75 administrative, acting, and technical interns and apprentices.
