GRINNELL, Iowa – When walking into this structure, typical conversation becomes hushed. This isn’t a church, but you could say it used to be a holy place of capitalism.  

The old Merchants’ National Bank in Grinnell is one of just a handful of banks designed by American architect Louis Sullivan. 

The board of Merchants’ National Bank approached Sullivan to construct the structure at a prominent spot in downtown Grinnell. The building was finished in 1914. 

Sullivan’s touches are notable all over the building. A stunning stained glass window is found on the east side of the building, so sunlight could shine down on the tellers. The tall ceilings culminate in blue stained glass along the ceiling. Onlookers will find intricate carvings inside and out.  

Sullivan hoped to cultivate a sense of security. From the outside, the building looks like a lock box. It feels and looks solid. Several of Sullivan’s banks have been named “Jewel box banks” for this reason.  

The building served as a bank until 1999. Now, it’s used by the Grinnell Chamber of Commerce. Ironically, a Wells Fargo is connected to the back of the building.  

Visitors are encouraged to stop in and check out the structure for themselves. It’s certainly a place where history, architecture, and art all intersect.
