Lilly's personal philanthropy also included contributions to the preservation and restoration of historic houses in Indianapolis and New Harmony, Indiana, and at Shakertown, Kentucky. Lilly, along with other Hoosiers interested in preservation, founded the Historic Landmarks Foundation of Indiana (now Indiana Landmarks) to aid in the preservation of structures significant to the historical and cultural development of Indiana. In 1962 Lilly purchased, restored, and furnished Kemper house, a Victorian home in Indianapolis, saving it from demolition. Later that same year, HLFI purchased a home in the historic Old Northside neighborhood of Indianapolis, which was named the Morris-Butler House for its previous owners, and with Lilly's help restored it to serve as a museum of mid-Victorian decorative arts and preservation education. With Lilly's assistance and a financial gift, the foundation also acquired the historic Huddleston farm in east-central Indiana in 1966 and restored its three-story, Federal-style brick home, which once served as a stop for travelers along the National Road.
