Town Character
Parker is a home rule municipality that identifies itself as a town under Colorado home rule statutes. In recent years it has become a commuter town at the southeasternmost corner of the Denver metropolitan area.
Early History
The first known people in the area were ancient and Plains Woodland peoples. Utes, Arapaho, and Cheyenne were present by the 1800s, establishing seasonal camps for hunting and gathering. Nearby Franktown Cave shows evidence of habitation from the early Archaic period through later cultural periods.
From Pine Grove to Parker
Stage roads followed historic Cherokee and Trapper’s Trails through the area. In 1864, Alfred Butters opened the Pine Grove Way Station in a small one-room building to sell provisions, manage mail and messages, and offer rest for travelers.
The building later became known as Twenty Mile House, named for its distance from Denver. James S. Parker bought it in 1870, added a blacksmith shop and mercantile store, and served as postmaster when a post office was established for the Pine Grove settlement. The settlement’s name changed to Parker in 1882, first as Parkers’ for James and George Parker before the apostrophe was dropped.
Historic Places
The restored Twenty Mile post office stands on Mainstreet just west of Parker Road. Ruth Memorial Methodist Episcopal Church is listed on the National Register of Historic Places, and other historic places include Parker Consolidated School, Hood House, Tallman–Newlin Cabin, and Parker Cemetery.
Parks, Trails, and Arts
The town maintains about 250 acres of developed parkland and more than 900 acres of open space. Parker also maintains trails, including concrete paved multi-use routes, natural-surface equestrian trails, and a natural-surface multi-use loop. The Cherry Creek Trail follows Cherry Creek north and south through town.
Parker is home to the Parker Arts, Culture, & Events Center, which hosts art exhibits, classes, theater productions, and concerts. It is the official home of the Parker Symphony Orchestra, and Colorado School of Dance partners with the center for the annual Nutcracker of Parker.
