Castle Rock

Benjamin Hammar House, Location: 203 Cantril Street, Castle Rock, Colorado 80104

National Register 2/3/1993, 5DA.645
The Italianate building was constructed in 1887 for Benjamin Hammer. One of Castle Rock’s earliest stone houses, the colorful local rhyolite stone was quarried from the Castle Rock district. The house is embellished with dressed segmental arches with keystones, reflecting the skill of the stonemason.

National Register 9/20/1984, 5DA.342
Completed in 1897, the two-story building includes a round arched entrance, bell cast roof, bracketed eaves, and tower. It was built of locally quarried rhyolite in colors ranging from pink and tan to gray. Despite several additions, it is the town’s finest example of stone construction and the area’s best illustration of the Italian Villa style.

Castle Rock Depot (Castle Rock Museum), Location: 20 Elbert Street, Castle Rock, Colorado 80104

National Register 10/11/1974, 5DA.216
The 1875 building is a rare example of a stone depot constructed by the Denver & Rio Grande Railroad. Castle Rock quarries yielded the high quality rhyolite stone used in the depot’s construction. A private owner moved the building to its present location in 1970 to serve as a private residence. The depot now serves as a museum.

First National Bank Building of Douglas County, Location: 300 Wilcox Street, Castle Rock, Colorado 80104

National Register 4/14/1995, 5DA.661
The 1904 building employs rhyolite, an igneous rock quarried in the Castle Rock area, on its two street-side facades. Similar to granite in appearance and composition, rhyolite was widely used in the Denver area. Denver architect George Bettcher designed the building. It represents the only known example of an architect designed, Romanesque Revival style building in Castle Rock.

Keystone Hotel, Location: 219 & 223 4th Street, Castle Rock, Colorado 80104

National Register 6/20/1997, 5DA.681
The 1901 two-story commercial building, along with its 1910 addition served as a social hub of the community. For many years it was the only hotel in town, and a saloon or restaurant continuously occupied the corner location from 1901 until the 1960s. The building is a good example of the use of locally quarried rhyolite.

National Register 3/19/1998, 5DA.1097
The cluster of buildings serves as the headquarters of the corporate arm of a Co-Masonic fraternal order. This organization is associated with early 20th century efforts to facilitate bargaining for better working conditions, and Co-Masonry reflected the trend toward the further emancipation of women. The group purchased the land in 1916 in order to establish a headquarters, a retirement place for coal miners, and a home for orphans and widows. The focal point of the complex is the Administration Building, constructed in 1924.

National Register 10/1/1974, 5DA.215
Although there are no visible remains, it is the site of Fort Washington, a log stockade that enclosed a homestead cabin and a large well. Built during the Indian Wars of 1868, it was a strong defense point for the entire West Plum Creek Valley. A later construction, the 1885 1½-story dwelling, was built utilizing locally gathered native stone and is a good representative of Douglas County stone architecture for the period.

The site is long associated with the conservation efforts of the U.S. Forest Service in Colorado. In continuous use since 1912, the site is the last full-time lookout in Colorado.

National Register 7/2/1999, 5DA.1391
The community, begun by the Du Pont Company in 1906, and occupied starting in 1908, provided employee housing and support facilities for the adjacent Louviers Works dynamite plant. Du Pont carefully planned, built, and managed the village. In addition to housing for workers and management, the community included a school, church, hotel, parks and a ball field, and a large community club. The community remained under Du Pont ownership until 1962, when the company sold both the village and the dynamite plant.

Louviers Village Clubhouse, Location: Louviers Boulevard & 1st Street, Louviers, Colorado

National Register 9/22/1995, 5DA.1016
Constructed in 1917 by E.I. du Pont de Nemours and Company, the club served as a social and recreational center for the company town of Louviers. Du Pont endeavored to establish a sense of community for its employees. The Craftsman-style club contained an assembly hall, a “women’s talk room,” a grocery store and a post office. It also boasted a two-lane maple-floored bowling alley with hand-loaded pin setters, thought to be the oldest continuously-used bowling alley in Colorado. Du Pont ran the club until 1963, when it leased the facility to the town. The plant closed in the mid-1980s, and the club now belongs to the county.

National Register 10/29/1975, 5DA.212
In the early 1860s, the Denver and Rio Grande Railroad’s first stop south of Denver was at Plum Creek, now known as Sedalia.

Santa Fe Railroad Water Tank, Location: South of Highway 85, west of the junction with Highway 67, Sedalia, Colorado 80135

National Register 4/18/2003, 5DA.1385
Constructed in 1906, the 140,000 gallon steel tank measures 24 feet in diameter and 43 feet in height.
