Minnesota towns list about as much on the Register as the country (a typical Minnesota town has 2.1 per 10,000 residents, the U.S. 2.4), so Sleepy Eye’s 26.1 sits above most of its state (88% of Minnesota towns have fewer) while its 9 historic buildings outnumber those of 75% of U.S. towns.

Sleepy Eye took its name from Sleepy Eye Lake, which was named after Chief Sleepy Eye, who was known as a compassionate person with droopy eyelids (or maybe just one). The chief was one of four Sioux Native Americans (four Ojibwe also attended) chosen to meet President James Monroe in 1824 in the nation's capital. Later, Sleepy Eye was an integral player in the 1851 signing of the Treaty of Traverse des Sioux, which gave all the land but a 10-mile swath on each side of the upper Minnesota River to the U.S. government. His recommendations to traders led to the successful settlement of Mankato, away from flood areas, and the chief eventually settled his people near the lake now known as Sleepy Eye Lake.
