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

Dr. William Worrall Mayo hand-built this small Gothic-style home in 1859. It was the birthplace of Dr. William James Mayo in June of 1861. Dr. Mayo set up his first medical practice in Minnesota form this home. Later in Rochester, Minnesota, Dr. W.W. Mayo and his two sons William James and Charles Horace founded the world-renowned Mayo Clinic.

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

From 1936 to 1967, the home served the community as the first Le Sueur Public Library.

The Mayo House is owned and was restored and warmly furnished to the 1860 time period by the Minnesota Historical Society.

From 1986 to 2013, the historic home has been operated by the Mayo House Interpretive Society, (MHIS, Inc) under a management agreement with the Minnesota Historical Society. In 2013, working closely with MHIS, Nicollet County Historical Society (NCHS) became the contract manager of the Mayo House.
