Setting on the Front Range
Castle Rock is a home-rule town and the county seat of Douglas County. It is part of the Denver-Aurora-Lakewood metropolitan statistical area and the Front Range urban corridor, at the junction of Interstate 25 and State Highway 86, 28 miles south of downtown Denver and 37 miles north of Colorado Springs.
The town lies a few miles east of the Rampart Range of the Rocky Mountains, on the western edge of the Great Plains. Its namesake butte stands just north of the town center, and other visible landforms include Dawson Butte, Devils Head, Mount Blue Sky, and Pikes Peak.
Creeks, Hillsides and Wildlife
East Plum Creek flows generally north through Castle Rock within the South Platte River watershed. Hangman’s Gulch drains toward East Plum Creek around the north side of the town center, while McMurdo Gulch and Mitchell Gulch run through eastern Castle Rock and drain into Cherry Creek east of town.
Castle Rock is in the Colorado Foothills life zone.
Settlement and Rhyolite
White settlers came to the area because of gold rumors and land opened by the Homestead Act of 1862, but rhyolite stone became the discovery that led to settlement. Castle Rock was founded in 1874, after the eastern Douglas County border was redrawn, and was selected as the county seat because of its central location.
Jeremiah Gould, an early homesteader south of the Rock, donated land for the new town. Streets, a courthouse square, and town lots were laid out, and a Denver and Rio Grande Railway depot later brought rail service. In the late 1800s and early 1900s, rhyolite quarrying was active, and many immigrants came to work in the quarries.
Historic Sites
The original Douglas County courthouse is among seven Castle Rock buildings listed on the National Register of Historic Places, along with the Castle Rock Depot, Castle Rock Elementary School, First National Bank of Douglas County, Samuel Dyer House, Benjamin Hammer House, and Keystone Hotel. The historic county courthouse, built in 1889–1890, burned in 1978 as the result of arson.
The Castle Rock Historical Museum is housed in the former Denver and Rio Grande Railway depot on Elbert Street. The building is described as being made of rhyolite from local quarries, and the museum presents changes in Castle Rock over time.
The Star and Parks
In 1936, Castle Rock received donated land that included the butte for which the town is named. Men employed by the Works Progress Administration built a star atop the butte soon afterward. The star was lit from 1936 to 1941, left dark during World War II, altered into a V-for-victory symbol in 1945, and later lit for the holiday season.
The town lights the 45-foot electric star on the Saturday before Thanksgiving, with a downtown event that is usually accompanied by fireworks. Castle Rock also has parks and open space covering 27% of town land, along with nearly 75 miles of paved and soft-surface trails. Philip S. Miller Park includes 300 acres and the Philip S. Miller Activity Center.
