Goodspeed Opera House, located in East Haddam, Connecticut. A distinctive feature of the view from the Connecticut River, the Goodspeed Opera House is the birthplace of some of the world's most famous musicals, including Annie, Man of La Mancha and Shenandoah. The Opera House was originally built by a local merchant and banker, William Goodspeed during 1876 and 1877. Despite the name, it was not in fact an opera house, but rather a venue for presenting plays. The building is unique for a theater. The theater itself is actually located on the top two floors of the building making for interesting and sometimes difficult scenery and show load-ins.—Wikipedia
