North Dakota past and present is uncovered at the state's largest museum and archive. In 2014, the museum was renovated and its floor plan enlarged to 39,000 feet. New permanent features include galleries focusing on different time periods in the history of the territory now known as North Dakota, from its ancient geological beginnings underwater to its current position as a modern agricultural producer. There’s also a large children’s wing, the Treehouse, as well
as a gallery devoted entirely to traveling exhibits. Note: at this writing the museum will be closed and will not reopen until November 2, 2014.
