Mayo House

This hand-built house held Dr. W. W. Mayo’s first medical practice, witnessed events of the US-Dakota War of 1862, and eventually served as the family home for another giant of Minnesota history — the Cosgrove family of the Green Giant Company.

Location: 118 North Main Street, Le Sueur, MN 56058

The Mayo House is managed in partnership with the Ney Nature Center and MHIS, Inc (Mayo House Interpretive Society.)  Both the Mayo Family and  the Ney Family arrived in this area of the MN River Valley in the mid-1850’s.  There is no way of knowing if the families knew each other but the general history of the time for settlers in the Le Sueur-Henderson area is shared.

2021 Open Season:

Costumed guides will lead you through the home while they share stories of the Mayo and Cosgrove families who lived here before founding the Mayo Clinic and the Green Giant Company, respectively.
