Wales Township was set off from Clyde Township by the state legislature on March 27, 1841, and it was considered one of the finest agricultural districts in St. Clair County. In 1889 citizens voted to build a town hall, and on November 8, 1890, the township board held its first meeting in this Stick Style building. The interior retains the original bench seating around the perimeter of the hall, which is still used for township meetings.
