Established in 1854 and successfully platted in 1855 the city of Rochester was originally a stagecoach stop between St. Paul and Dubuque in Iowa. With the establishment of the railroad in October of 1864 more settlers and businesses came in as a result.  Notable personalities like Dr. William Mayo arrived in 1863 and established the world-famous Mayo clinic.  2004 saw the sesquicentennial celebration of the city.
