Perched on a bluff over the intersection of the Minnesota and Mississippi rivers, Fort Snelling is an outpost that long outlived its original purpose.

In the 1820s, long before Minnesota was a state, the fur trade was the cornerstone of commerce in the new world. The fort was built to protect the industry.

Not more than a few decades later, the fur bubble had burst, and Fort Snelling took up other roles. It oversaw the uprooting and relocation of Native American tribes in the area and acted as an induction station for the U.S. Army during every major conflict through World War II.

It was decommissioned in 1946 and designated a historic landmark in 1960.

Today, the fort’s historic buildings have been restored as a museum that’s manned by a small army of reenactment soldiers. They even have a cannon.
