We recently visited on a Sunday morning...and...it was not busy at all. We have been here before but...it had been several years. They have many permanent exhibits...along with other temporary ones. Some of our favorites are: 'Then...Now...Wow!'...and...the tornado simulator in the 'Weather Permitting' gallery. The two-story wooden play structure replica of a grain mill [Grainland] is a huge hit with little ones. You can go inside an actual-sized tipi...mud house...or...even an old Saint Paul streetcar. Minnesota has deep roots in Native American culture...history...and...heritage...and...you will find quite a few references to that impact at the History Center. It is an entertaining option for most age groups...from younger to older...as there are many hands-on pieces to learn from. I would say you could spend around two hours here to get the full experience. They do have a research library onsite...hours are by appointment only. There is also a gift shop...auditorium...and...a small cafe with light dining options. It is conveniently located right in downtown Saint Paul with both the state Capitol...and...Cathedral of Saint Paul just a few short blocks away. You get nice views of each from different places inside/outside the History Center. There is a paid onsite surface parking lot...pay as you enter...with plenty of spots. We really dig this place...it's always fun to return to see favorites...and...appreciate the visiting exhibits. If you get the chance...definitely check this place out...you won't be disappointed.
