The League of Historic American Theatres, Inc. (LHAT) is a non-profit membership association founded in 1976 by 42 charter theatre members. The League has grown into a network of more than 300 historic theatres throughout the United States and Canada. Past and current League members have driven the rescue and rehabilitation of hundreds of historic American theatres for more than three decades. The mission of the League of Historic American Theatres is to champion the preservation, restoration and operation of historic theatres. LHAT envisions these unique showcases for human creativity, arts and culture as vital assets in livable communities throughout North America. We believe that historic theatres are irreplaceable social, economic, historic and cultural resources for their communities. As iconic, creative places of public assembly, they build community loyalty, reinforce community identity and heritage, stimulate downtown revitalization, promote pride of place and anchor creative economies. In recent years, the League and its members have become increasingly focused on identifying and sharing the tools, techniques and technologies required to sustain historic theatres as the center of their communities. We want to insure that historic theatres, ones that have been restored through extraordinary community efforts and at considerable expense during the past several decades, can be sustained for the benefit of future generations. By focusing on how to sustain operating theatres, the League can better serve the field and assist emerging theatre projects. Recognizing issues and challenges unique to historic theatres, the League facilitates information exchange among members through peer interaction, conferences, and collaborative projects.
