The Calhoun Rock Garden, a community rock garden north of Atlanta, attracts thousands of visitors a year. The original creation of these miniature dwellings was created by Dewitt Boyd, known as "Old Dog," who used stones to connect his children and grandchildren. Over a decade, he and volunteers gathered thousands of stones, along with tiles, shells, and broken glass and china, then combined them together with his signature sculpture material, wire and cement. He created replicas of landmarks and religious sites such as Bethlehem and original castle designs. The garden was not intended to be a tourist attraction but has become a popular attraction. When the Boyds moved away in 2019, fellow church members Mike and Jan Miller took over caretaking. They are currently maintaining the structures and the garden.
