Wawatam Township in Mackinaw City in Cheboygan County, Michigan — The American Midwest (Great Lakes)
The Powder Magazine
The mound to your right is the powder magazine. Originally built in the mid-1730s by French civilians, the magazine provided a safe place to store gunpowder, musket balls, gun flints, and other ammunition.
British soldiers repaired the structure in 1772, and during the American Revolution the magazine housed supplies to arm the garrison and Native American war parties. In 1779, Lieutenant Governor Patrick Sinclair decided to relocate the entire community to Mackinac Island. The underground magazine could not be moved, so British soldiers set it on fire in 1781. As it burned, the roof collapsed, smothering the fire and leaving behind well preserved log walls, floorboards, and an entrance stairway. Most of the structure remained undisturbed until excavated by archaeologists in 1974-75. Today, the powder magazine is the largest and best-preserved original structure at Michilimackinac.
