The National Trust Main Street Center is a program of the National Trust for Historic Preservation. In the 1970s, the National Trust developed its pioneering Main Street approach to commercial district revitalization, an innovative methodology that combines historic preservation with economic development to restore prosperity and vitality to downtowns and neighborhood business districts.
Today, over 1,700 communities in 37 states utilize the Main Street Approach. Throughout these communities, nearly 100,000 buildings have been rehabilitated across the United States, and the amount of public and private investment in physical improvements tops $17 billion. For every $1 invested through public and private sources in Main Street projects nationwide, an average of $32 is reinvested in the community.
