Come explore a piece of Minnesota history at the W.W. Mayo House in Le Sueur.

Dr. William Worrall Mayo hand-built this small Gothic-style home in 1859. Dr. Mayo set up his first medical practice in Minnesota from this home. Dr. W.W. Mayo and his two sons William James and Charles Horace went on to found the world-renowned Mayo Clinic.

Between 1874 and 1920, it was the home to three generations of the Carson Nesbit Cosgrove family of the Green Giant Company history. Seven children from the second and third generations of the family were born in the home, including two Green Giant Company presidents.


Closed for the season, except for special events, through May 2020.
