Main Street Greensburg promotes and serves Greensburg’s iconic downtown by honoring its unique history, strengthening its economic vitality, and cultivating growth while remaining rooted by the famous Decatur County Courthouse tower tree. We are a public/private entity that was founded in 2005 with a commitment to preserve and support the downtown community. As a member of the National Main Street Center and the Indiana Main Street program, the organization is driven by the Main Street Four-Point Approach — organization, promotion, design, and economic restructuring.
