As is often the case when new courthouses are established in a downtown area, the commercial buildings around the courthouse go through substantial renovations often to mirror the new architecture of the courthouse if not in style, certainly in impressive detail. Such was the case opposite the courthouse in Rensselaer when three notable buildings sprung up.
A great moment in Jasper County history was when President Dwight D. Eisenhower spoke at the courthouse in 1962 to honor Rensselaer resident Charles Halleck. Halleck was a member of the US House of Representatives from 1935-1969. The downtown was placed on the National Register in 2011.
