The Mexico Business Men's Association was founded in 1898.  One of its first projects was to lead the way in the re-establishment of Missouri Military Academy after an 1896 fire destroyed the original.

In 1911, this organization evolved into the Mexico Civic Club.  This group acted in city and county government positions and was active in the Audrain County Fair.  It also conducted homefront war activities.  The Civic Club had its offices in the Hotel Hoxsey on the square.

In 1945, the Civic Club reorganized into the Mexico Chamber of Commerce, and joined the Missouri State Chamber in 1948.  Between 1945 and 1996, the offices moved to four different locations around the square.
 

Mexico Savings Bank was founded in 1861 by A.R. Ringo.  Its final home was built in 1935, where in the 1970s it evolved into part of Commerce Bank.  In 1996, two historical icons of Mexico came together when the Chamber relocated its offices to the former bank.  After major renovation, the building is now host to meetings of Chamber committees and other community clubs and organizations. Also housed in the building is the the Vault Gallery (an outlet for local artists) and an extensive collection of Mexico memorabilia.
