William Harris constructed his Foursquare type residence circa 1910.  Harris, a prominent cattleman in the Sterling area, was involved with irrigation projects and served in the state legislature in 1901-1902.

The 1919 First Presbyterian Church is one of Sterling’s most outstanding structures architecturally and a major local landmark because of its visual qualities. 

The 1927, blond brick Gothic Revival style building is important for its association with a specific ethnic group, Germans from Russia. 

The Downtown Sterling Historic District is significant for its long association of providing the residents of Sterling and surrounding areas with goods and services since 1896. 

Constructed in 1915, the red brick, Late Gothic Revival style church is a relatively small building that includes a considerable amount of detailing in its brickwork and the tracery of its Gothic arched stained glass windows.

The Powell and Blair Stone Ranch ranch house, built between 1897 and 1898, is representative of the most common version of the American Foursquare, with its simple square plan, low-pitched hipped roof, and symmetrical facade.  The house, bunkhouse, and stone outbuilding are significant for their use of locally quarried stone.

The 1910 house is a good local example of an early 20th century masonry building constructed with native stone.  The house is one of the few remaining known examples of stone construction in Logan County.

Since the creation of the Walks Camp Park Association in 1915, the agricultural community north of Limon has operated the park as a recreational complex. 

The Lincoln Theatre is Limon’s longest surviving movie theatre.  Opening in 1938 as the Cactus Theatre before assuming the Lincoln name in 1949, the theatre has operated continuously to the present.  

The town’s location at the intersection of the Union Pacific Railroad and the Chicago, Rock Island and Pacific Railroad, and its designation as a division point on the latter, made Limon an important regional rail center and a major source of local employment.  The 1910 wood frame depot is one of only three Rock Island depots in Colorado remaining in their place of operation.
