North Dakota towns list about as much on the Register as the country (a typical North Dakota town has 2.8 per 10,000 residents, the U.S. 2.4), so Grand Forks’ 118 sits above most of its state (97% of North Dakota towns have fewer) while its 696 historic buildings outnumber those of 98% of U.S. towns.

What stands out about Grand Forks’ past
Read from the archive, the National Register and the record. The page puts what stands out first.
Before Europeans arrived, the area where the city developed, at the forks of the Red River and Red Lake River, had been an important meeting and trading point for Native Americans for thousands of years. Early French explorers, fur trappers, and traders called the area Les Grandes Fourches, meaning "The Grand Forks". By the 1740s, French fur trappers relied on Les Grandes Fourches as an important trading post. This was French colonial territory.
