The story that haunts this land
Your investigation in Corydon begins at Indiana's First State Capitol, a two-story brick building constructed in 1816. This building served as the seat of Indiana's state government from 1816 to 1825, before the move to Indianapolis. It was here that Indiana's first constitution was signed in 1816. Restored between 1913 and 1917, this National Historic Site has been open to the public as a museum since 1929. You will search for the first traces of Morgan's message, perhaps hidden in official archives, as you explore this monument to Indiana's heritage.
A short walk away, the Constitution Elm Memorial commemorates the elm tree under which Indiana's constitution was drafted in June 1816. The original tree was cut down in 1929, but a memorial plaque is installed near the First State Capitol, bearing witness to the constitutional convention held from June 10 to June 29, 1816. This is a key location for understanding the foundations of the state, and potentially for deciphering codes related to the ideals of the founding fathers. Your archivist mission compels you to examine every detail, every inscription of the National Register of Historic Places.
The route then leads you to the Harrison County Courthouse, built in 1927-1928 in a Neoclassical style with a copper dome. It has been the seat of Harrison County government since 1929, replacing earlier structures, and was listed on the National Register of Historic Places in 1993. Although more recent, this building embodies the continuity of local administration and the preservation of order, contrasting with the chaos of the Civil War. Here you might find records related to the 1863 events, clues about Morgan's Raid that shook the region.
A crucial moment of your quest takes place at the Battle of Corydon Memorial. This memorial commemorates the Battle of Corydon which occurred on July 9, 1863, during Morgan's Raid. It was the only Civil War battle fought in Indiana, where 355 Union soldiers were captured. Located near the site of the clash where John Hunt Morgan's Confederates defeated local militiamen, this place is steeped in history. It is here that General Morgan reportedly left a vital clue, a final message before continuing his journey.
Your exploration of Corydon concludes with the Posey House, a historic home built around 1835, named after Thomas Posey, Indiana's second governor (1816-1819). Listed on the National Register of Historic Places in 1973, it is an example of typical early 19th-century Federal architecture. Then, The Kintner House Inn, built in 1870 in the Second Empire style and listed in 1997, still operates as a hotel-restaurant. These places, witnesses to Corydon's evolution and Indiana's heritage, could well house the last pieces of the puzzle, allowing you to reconstruct "Morgan's Last Message" and understand the lasting impact of Morgan's Raid on the history of this town.
