Mankato Lodge No. 12 AF & AM is one of the most historic lodges in the state of Minnesota, and was in-fact formed two years prior to Minnesota’s statehood. Over the past 150+ years, we have striven to help our members grow into the men that they seek to become. We meet at 7 PM on the second and fourth Tuesdays of every month, and go dark during the months of July and August. Our lodge is located in our historic building at 309 S. 2nd St, Mankato, MN 56001. Please see our calendar below for details. For more information on the history of our lodge, feel free to use the files located below.
