Updated Open-Dates For Minnesota Historic Sites + Museums The Minnesota Historical Society (MNHS) has announced their plans in regard to updated open-dates for a wide variety of museums and historical sites that they maintain across the state. Many of these sites have been shut down since last March when the earliest shutdown and stay-at-home orders were given due to the COVID-19 Pandemic. With COVID-numbers stabilizing and with the roll-out of vaccines, the Minnesota Historical Society is "pleased" to welcome back visitors to these unique tourist sites. Some of the sites are already open. Others will start to open to visitors - in a staggered, tiered-roll out - beginning the end of May. Meanwhile, the Minnesota Historical Society is working on plans to reopen others.
