The Putnam Courthouse, holding various court and law functions, has a classical design of the late 1940s and early 1950s, although it was actually constructed in 1966-67. In small towns and rural areas such as where Putnam is located, it is not surprising to see earlier styles still employed. The architect was Willard Wilkins, based out of Hartford.
The design focuses on symmetry to give a more imposing quality. The facade is unified by limestone boxes around both the first and second floor windows with a central panel of black granite between them.
