This was the home of the Phoenix Mutual Life Insurance Company until its move into the dramatically different "boat building" on Constitution Plaza in 1963. Located at 61 Woodland Street, the building became the home of Greater Hartford Community College (now Capital Community College) from 1974 to 2002. It's now the headquarters of the Connecticut State University System.
The back reads: "The Phoenix of Hartford Insurance Companies Home Office building, Hartford, Connecticut. The Phoenix Companies write all forms of insurance except life."
