Historical Note

In July 1871 the General Assembly created a commission and authorized a bond issue and the expenditure of funds to plan and construct a new State Capitol building in Hartford. The old State House was to be turned over to the city.

The first Board of State House Commissioners accepted plans drawn by Richard M. Upjohn of New York and awarded a construction contract to James G. Batterson. In the middle of 1873 the General Assembly suspended the work and appointed a new commission to direct changes and improvements in the design and specification; as a result the building was made “fireproof”, it was considerably enlarged, and the planned modest clock-tower was replaced by the imposing gilded dome.

The building was completed and occupied in 1879.

The Board of Capitol Commissioners oversaw construction of a new State Capitol building in Hartford.


The Commission (which still sometimes called itself the State House Commission) turned over “the last of “ its files to the Comptroller on 30 November 1880, with an itemized list. Those records were transferred in March 1974 from Vault 2 in the Capitol basement to Archives in the State Library.
