NCHS is temporarily closed due to COVID-19

*** Our museums remain closed temporarily due to community coronavirus concerns. ***

Visitors are immersed in aspects of Victorian daily life through tours, programs, meetings, and social events at the E. St. Julien Cox House. This historic house museum is a place to relive history, gather for community discussion, entertainment, and fellowship.

Eugene St. Julien Cox and his wife Mariah “Mayhew” Cox built this home and raised their family here. The women raised in this house went on to make local and state history. The Cox House interprets the lives and experiences of Victorian women and tells those stories in dynamic ways to diverse audiences.

Eugene Cox was one of the earliest settlers of St. Peter, an attorney, St. Peter’s first Mayor, and a representative to the State House and Senate. The Home was built in 1871 and is one of the few fully restored Italianate homes in Minnesota. His daughter Lillien Cox Gault followed in her father’s footsteps and would eventually become Minnesota’s first female mayor. Her sister Irene would be one of Minnesota’s first female attorneys.
