The Old Capitol building, a part of the Corydon Capital State Historic Site, is administered by the Indiana State Museum and Historic Sites.
The two-story, Federal-style, limestone building served as Indiana's first state capitol from 1816 until 1825.
The building was originally intended to serve as the Harrison County Courthouse.
Construction began in 1814, when Corydon was the capital of the Indiana Territory.
The building was nearly completed in 1816, the year that Indiana was granted statehood and its first state legislature convened at Corydon.
The building was primarily used as an assembly building for the territorial and state legislatures, but the county government and district courts occasionally used it when the Indiana General Assembly was not in session.
Dennis Pennington, who became the state's first speaker of the Indiana Senate after statehood in 1816, supervised its construction.

The two-story building is 40 feet (12 m) square with walls 2.5 feet (0.76 m) thick.
The exposed exterior of the building is not dressed, using only stones that were cut roughly square.
The foundation, dug 3 feet (0.91 m) into the ground, is also 2.5 feet (0.76 m) thick.
The lower level has 15-foot (4.6 m) ceilings, flagstone floors, and a barn rail made from hewn timber.
The upper floor's ceiling is 10 feet (3.0 m) tall.
The original building had a scale and balance on the roof as the symbol of justice, but they were removed in 1833 and replaced with a large bell.
The construction cost of original building was approximately $3,000.
Two large chimneys that accommodated the four fireplaces installed in both the upper and lower levels were closed up during later renovations.
A wood floor covered the original flagstone floor.

When Corydon became the state capital of Indiana in 1816, the Old Capitol building served as the seat of state government.
The Indiana Supreme Court and the Indiana Senate were located on the upper level; the Indiana House of Representatives met on the first floor.
After 1825, when the state capital was moved to Indianapolis, the Old Captol building continued to be used as the Harrison County Courthouse and county government office building until 1929, when a new county courthouse was completed.

In 1917, the State of Indiana purchased the Old Capitol building with the intention of preserving it.
The restored building opened in 1929 and has since been preserved and protected as a memorial.
The Old Capitol, sometimes referred to as the Corydon Capitol, was included within the original boundaries of the Corydon Historic District when it was listed on the National Register in 1973.
The building has been restored as closely as possible to its original appearance, including furniture and paint colors.
In 2015, a major restoration project was completed on the town square to protect the Old Capitol building from water damage, to update the electrical system and landscaping, and to install new walkways.
