Constitution Elm at Corydon Capitol State Historic Site at 202 E. Walnut St. Corydon Capitol State Historic Site commemorates Indiana�s first state capital and follows the development of Indiana from a territory to a state. Vincennes, the first territorial capital, was left on Indiana�s western edge when the Illinois Territory was created, and in 1813, the capital was moved to Corydon, a more central location for Indiana�s population at the time. In June of 1816, 43 delegates met in Corydon to draft the first state constitution. Much of their work was done under the shade of a large elm tree. The trunk of the tree, now known as �Constitution Elm,� is still standing. The first state election was on Aug. 5, 1816, in which Jonathan Jennings was elected governor. In November 1816, the first General Assembly of 29 representatives, 10 senators and the lieutenant governor met in the new capitol building. On Dec. 11, 1816, Indiana was formally admitted as the 19th state. Corydon remained the state capital until the government moved to Indianapolis in 1825. The square, Federal-style capitol building, built between 1814 and 1816, is located in the heart of downtown Corydon. Workers hauled limestone from nearby quarries to erect the 40-foot square walls, and logs were cut from virgin forests for the ceiling and roof supports. After the government moved to Indianapolis, the building was used as the Harrison County Courthouse. When the present courthouse was completed in 1929, the old capitol building was restored and opened as a state memorial in 1930.
