Founded in 1983 the museum was originally located in the house at 818 Geneva Street.  In the 1990’s the city moved the Waterworks Department, which had been housed in the 1929 Wisconsin Power & Light building, to a new larger facility.  The Geneva Lake Museum leaders persuaded the city to let them use the old building for a museum. In 2004 the museum moved to that building at 255 Mill Street. Taking advantage of the generous space the new building provides, the Museum Board along with  much volunteer help, created Main Street, Lake Geneva.  There was ample room left over for additional display areas, a museum store and meeting rooms.
