W. W. Mayo House

MNHS Mayo House Logo

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

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.

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-1850s. There is no way of knowing if the families knew each other but the general history of the time of settlers in the Le Sueur-Henderson area is shared.

Art Day at the Mayo House

Tuesday, June 18th, 9:30am-11:30am

Just like kids today, many children in the 1800s enjoyed making arts and crafts. If you are one of those kids who loves art, we think you’ll love “Art Day at the Mayo House,” a two-hour event where you can learn about arts and crafts that were popular in the middle of the nineteenth century (the 1800s). We will make colored tin tiles and woven baskets and learn about the differences and similarities between the art of 150 years ago and the art of today. Pre-Registration is required. Ages 10+.
