Local farmers organized Hamilton Grange No. 355 in 1874 and built Hamilton Grange Hall the following year. Because the area lacked a town center, residents gathered there for elections, rallies, school programs, church services, funerals, lectures, and parties. By 1897, No. 355 was among the largest granges in the state and held annual fairs on adjacent land. The Hamilton Grange hosted the "Great Free Fair" each year from 1878 until around 1913, when the county fair began. People came to hear speakers, watch horse races, attend picnics, and view exhibits at fairgrounds just north of the hall, where farm families competed with produce, livestock, bread, canned goods, floral arrangements, and needlework. In October 1905, more than five thousand spectators from the Hamilton area came to hear Governor Fred Warner. When the grange disbanded in 1977, the building became Hamilton Township Hall.
