Altura is a town in Winona County, Minnesota, United States. The population was 493 at the 2010 census.
Altura started out as a hunting ground for the Sioux Indians. They hunted deer, bear, wolves, quail, and other game native to the area. They also trapped mink and muskrat in the streams that now run through many of the farms. The Sioux Indians were here until 1853 when they signed the Treaty of Traverse Des Sioux, and the Treaty of Mendota, which made the territory available for settlement.
When the Sioux Indians left, the government offered the land for $1.25 an acre to the settlers for staking their claims.
