Capitol history
- Illinois' Sixth Capitol Building: Ground was broken for the present Capitol on March 11, 1868; the first stone was set in place a few months later. The formal laying of the cornerstone occurred on October 5th, 1868. Two years later the cornerstone developed large cracks and had to be replaced. Although still unfinished after eight years of work, the General Assembly moved into the building in 1876. The project was continually plagued with trouble. Corruption was suspected several times and at least one workman was killed on the job. Construction continued intermittently for twenty years. During this time there was a serious movement afoot calling for the abandonment of the unfinished structure and the Capital's removal to some other Illinois city. Civil War veteran Richard J. Oglesby was Governor when the building was started and was serving a third term when the Capitol was finally completed two decades later in 1888.
