Research Center Hours

Construction on the New Montana Heritage Center has begun! Parking can be more challenging. You may need extra time, and patience, when parking for your visit to the Research Center. Since the area around the Montana Historical Society is an active construction site, please be aware that there also may be construction noise during your visit or unexpected closures. For questions, please contact us at mhslibrary@mt.gov.

We are open to the public on:
