Discovery Park of America is filled with artifacts, replicas, history, science, art and more. Our mission is to inspire children and adults to see beyond, and we do so by sharing educational content online and throughout our museum.
We share weekly updates on anniversaries and significant moments in history, and where you can find items related to these dates through our museum and heritage park.
