Located at 603 Quincy Street in downtown Hancock, Michigan, Old Main (OMi) opened on January 21, 1900 serving as Suomi Opisto (Finnish College).

Today OMi (Old Main Inn) is privately owned and serves as a retreat center, wedding/event venue, museum and houses an artist collective and gallery.

[2] Suomi quickly outgrew Old Main, and an additional frame building housing a gym, meeting hall and music center was constructed in 1901.

Old Main is a four-story Richardsonian Romanesque building constructed from rough Jacobsville sandstone, which was quarried at the Portage Entry of the Keweenaw waterway.

[5] The building originally contained everything required for the young college: a dormitory, kitchen, and laundry, as well as classrooms, offices, a library, chapel, and lounge.
