The Institute was founded in 1963 with a mission to serve the historical outdoor drama movement in the United States.  Since then our mission has expanded to include all types of outdoor theatre from countries throughout the world.  Shakespeare festivals, musical theatre, religious and historical plays and all other forms of outdoor theatre are featured on this website. Our scope includes a wide variety of professional and community theatre organizations whose performances may run throughout the summer season or for only a few presentations. These organizations are united by their dedication to producing outstanding theatre and their unique position as providers of exceptional entertainment for their audiences.

Our goal is to provide a link to every outdoor theatre in the world through this website. If you are a theatre company producing any part of your work outdoors and you are not listed here, please contact us so that we may add you to the list.  There is no charge for this service.

Membership and Support: In addition to our international directory of theatres, the Institute provides additional benefits to members and supporters whose contributions help fund our work.  Consulting services, conferences, auditions and special publications are among those benefits.  Membership and support options are listed under the “Participate” menu on our home page.
