Home to three exhibits:
“Coming Together at the Straits: The People of Michilimackinac,” showcasing how the thriving community of Michilimackinac drew people from diverse cultures - many in search of wealth or to protect the British empire. Others had little choice, coming as slaves.
“Firearms on the Frontier,” which describes the various firearms used at a frontier outpost such as Michilimackinac.
The Powder Magazine is the most complete ruin at Michilimackinac.
The Powder Magazine and “Firearms on the Frontier” are both located down a flight of stairs. An accessible program is located at the entrance to the South Southeast Rowhouse.
