History

Arapahoe County has a rich, vibrant history and the distinction of being Colorado's first county. Named for the Arapaho Indians, who along with the Cheyenne Indians occupied most of Colorado when it was only a territory, it spans 805 square miles and is a land of contrast. The western part of the county is mostly urban with residential, retail, office and industrial areas, while the eastern portion is relatively rural.
