The Union Square Theatre, on the southeast side of the Square, was next to the Union Square Hotel. It Opened in 187 as a variety house and was transformed into a legitimate theatre the following year. Originally the most prestigious dramatic house on the Square, it faltered after a series of managers who tried to continue the tradition of serious fare, and became a vaudeville house which enjoyed a successful twenty year run under the management of B.F. Keith and E.F. Albee.
