Seventeen Mile House, Historic house in Centennial, US.

Seventeen Mile House is a historic residence in Centennial featuring square log construction covered in clapboard siding on a 33-acre property. The building sits along South Parker Road and preserves both interior spaces and the surrounding landscape from the era when it served travelers and farmers.

The Seventeen Mile House opened as a way station on the Smoky Hill Trail after the 1858-1859 Colorado Gold Rush brought wagon traffic toward Denver. Mary Hightower, the original owner, moved there in 1866. When railroad service reached Denver in 1870 the wagon trails fell into disuse, and by the 1880s the station had closed and become a working farm beside Cherry Creek. It is one of only two surviving way stations on the trail, the other being Four Mile House.

The house stands as one of few remaining buildings from the Smoky Hill Trail era and shows how settlers lived in early Colorado. It represents an important part of how people shaped this region and the role such way stations played in local community life.

Visitors can explore the house and grounds through monthly guided tours organized by the Cherry Creek Valley Historical Society. It helps to check tour dates in advance and come prepared for walking on a large property with natural terrain.

The stations along Cherry Creek were named by their distance from the intersection of Colfax and Broadway in downtown Denver; Four Mile House is the only other survivor. The site was zoned for commercial development until Arapahoe County acquired the land in 2001, and a 1977 demolition plan was stopped by negative publicity.
