The 1911 First Baptist Church, a rectangular plan building on a raised foundation, topped by an unenriched parapet in a Neoclassical style, was designed by architect T. Robert Wieger.

The 1905 Coronado Building is associated with the development and evolution of Greeley’s downtown and with Dr. Ella Mead and architect Bessie Smith, two women important to the community’s social history.  Smith’s design is an important local example of early 20th century commercial architecture. 

The 1916 Student Union stands as an important record of New Deal construction programs in eastern Colorado, reflecting the extensive assistance the Colorado State College of Education (now UNC) received from the PWA to remake its campus during the 1930s.  The building was the center of social life for the students of the College hosting events such as teas, mixers, dances, and banquets. 

The 1920 Conrad Borgens House is architecturally significant as a good example of a Craftsman style residence.  Builder and carpenter Conrad Borgens designed and built this house for his family and included Craftsman character-defining features including wood-shingle siding, lap siding, a full-width front porch with massive battered piers, exposed rafter ends, broadly overhanging eaves, multi-light-over-one wood frame sash windows, and gabled dormers with wood shingle siding. 

The 1920 Ottesen Grain Co. Feed Mill functioned as the sole grain buyer and livestock feed processor for the Fort Lupton area for over fifty years. 

This two-story brick building was constructed in 1906 and continued to operate as a school until 1966.  It has a hip roof with flared eaves, and the entry is topped by a bell tower.

Aaron James Eaton, the “Father of Commerce” in Eaton, moved into the new house with his family in 1888.  Eaton was one of the town founders, being active and influential in many aspects of community and regional development.  He established and operated the town’s first general merchandise store, the First National Bank of Eaton, and the Eaton Building and Loan Association.

The 1929 Eaton High School is important for its association with the history of education in Eaton. 

The 1925 Amanda K. Alger Memorial Methodist Episcopal Church is an excellent example of the Late Gothic Revival style popular in the 1920s.  Designed by the architectural firm of Wilson and Wilson, the church exhibits many of the characteristics of the style including a steeply pitched roof, arched windows with tracery, quatrefoil elements, a crenellated parapet, and simpler detailing. 

Designated under the Multiple Property Documentation Form for New Deal Resources of Colorado’s Eastern Plains at the state level of significance, the LUP Headquarters, mandated by the Resettlement Administration in 1935, is significant in the area of Politics/Government for its association with President Franklin Roosevelt’s New Deal legislative agenda to rescue the United States from the Great Depression.
