Director of the Minnesota Historical Society Nina Archabal is stepping down. Archabal has served as the society’s director for the past 23 years, and its deputy director for nine years prior to that. Under her leadership, the Minnesota History Center has grown into the state’s premier history museum and library, and the society created the Mill City Museum. The historical society is also responsible for a statewide network of historic sites and museums, including Historic Fort Snelling, Split Rock Lighthouse, the James J. Hill House and the Mille Lacs Indian Museum. Archabal says she will continue to serve as director until her replacement is found, which she expects to be no later than the end of this year.
