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.
