The Seventeen Mile House is a historic site and open space located at 8181 S. Parker Rd. in Centennial, Colorado. It is a 33 acre former stagecoach stop with a square log structure covered with clapboard. It was a stopping place during the 1800s along the Smoky Hill Trail. It is one of the last two remaining trail houses left on the trail. Mary Hightower was the original owner of the house, having moved there in 1866. It was almost torn down in 1977 until negative publicity stopped it from happening. The site was zoned for commercial development until the County of Arapahoe acquired the land in 2001.
