Lee is noted for its strong ties to Norwegian American culture. In fact, all of the streets in the village have Norwegian names. In 1974, in honor of the town's centennial, a contest was held to rename the streets and Mary Ellen Prestegaard's entry was chosen. She ran a shop in the village called the Hardanger Hus that sold Norwegian gifts. Many of the original citizens of the community came from the Hardanger region of Norway, and there are still many community members that can trace their ancestry back to that region.
