First state office building at 202 E. Walnut St. The recently-renovated First State Office building, built in 1817, was home to Indiana's first state auditor and treasurer. It is said that the money for the young state of Indiana was kept in a vault in the cellar. The building is now used to host programs and is available as a rental facility.
