What stands out about Westminster’s past
Read from the archive, the National Register and the record. The page puts what stands out first.
Gold discovered in the South Platte River Valley in 1858 brought national attention to the area that would become Westminster, Colorado. The promise of fortune and The Homestead Act of 1862 encouraged many pioneers from the east to settle in Colorado rather than continue on to California. Before the settlements came, wildlife like antelope and buffalo made their homes in the area. There is also evidence of Arapaho Indians near the Crown Point (Gregory Hill) area.
