What began as a modest concrete fish pond in H.G. (Ben) Hartman’s back yard is now revered as a folk art masterpiece. The Hartman Rock Garden includes over 250,000 individual stones that combine a mixture of history, religion and depression-era pop culture. Among the Hartman Rock Garden’s many unique attributes, the sheer scale of the work and its contextual location in a residential neighborhood, contributes greatly to its status as an iconic “outsider” art site. Fully restored by the Kohler Foundation in 2009, the Garden is open daily from dawn to dusk with no admission charge.
