Hannibal has five distinct Historic Districts recognized by the National Register of Historic Places, which include more than 500 buildings and structures dating from as early as 1839.


Historic preservation is of primary importance in Hannibal. In 1911, just one year after Mark Twain's death, Hannibal native George A. Mahan purchased Twain's boyhood home and thus began a life-long commitment in celebrating Mark Twain's legacy in Hannibal. Mahan, who would also serve as president of the Missouri Historical Society, was a pioneer in the notion of "heritage tourism" and many of the historic preservation projects he championed throughout Hannibal and across Missouri are still lovingly being maintained more than one hundred years later.
