Historic properties in downtown that are listed on the
Greeley Historic Register (GHR), the State Register and/or the National Register of Historic Places:

Lincoln Park (b/n 7th & 9th Sts, 9th& 10th Aves.) John F. Sanborn platted Lincoln Park in 1870 in the first plat of Greeley, done on a piece of brown wrapping paper. It is one of very few remaining sites constructed during the Union Colony's first year, and its history reflects the growth of Greeley's downtown area. For more information see walking tour stop of Lincoln Park.

Camfield Court Building (615-631 8th Ave.) This commercial building was designed by the Roeschlaub & Son architectural firm and was built between 1909 and 1911. It was primarily financed by Daniel A. Camfield, who also owned the Camfield Hotel, formerly the Oasis. A welcome arch, built in 1911, connected these two structures which were located diagonally across from each other.

Union Pacific Depot (902 7th Ave.) Gilbert Stanley Underwood designed this depot for the Union Pacific in 1930, replacing a stone depot that had been in use for more than forty years. It is Modern Classical style architecture and is typical of pre-Depression railroad depot architecture.

Oak & Adams House (930 5th Street) This vernacular masonry house features an engraved stone bock with the street names "Oak" and "Adams," reflecting Greeley's street names prior to 1884. This is the only remaining physical or architectural reminder of the old system.

Greeley Building (710 11th Avenue) This Romanesque Revival style high school, designed by Harlan Thomas in 1895, is the oldest high school building remaining in Greeley. The Classical Revival style addition was built in 1902-1903 due to overcrowding.

Greeley Tribune Building (714 9th Street) Sidney Frazier designed this Beaux-Arts style structure in 1928 to house the Greeley Daily Tribune offices and presses. Originally published in 1870 by town founder Nathan Meeker, the Tribune was consolidated with a competing publisher by Charles Hansen in 1913. Hansen published the Tribune from 1913-1953 and actively supported the development of irrigation.

Buckingham Gordon Building (810-816 9th St.) This building was constructed in 1907 by G.H. Gordon and George W. Buckingham, of Boulder. The 810-812 portion was restored by the Home Light and Power Company in 1977-1978. This building reflects commercial architecture of the early 20th but also exhibits elements from the late 19th century.

Coronado Building (900 9th Ave.) This commercial building was designed by Bessie Smith and constructed in 1905-1906. It is an important part of the historic downtown area, and is important for its association with Bessie Smith and Dr. Ella Mead, both famous pioneering women in Greeley.

Hawes Building (810-812 8th St.) This 1903 commercial structure was built for Mrs. Clementine Hawes after the death of her husband. It is important as representative of commercial architecture of the early 20th century.

New Cache La Poudre Irrigation Company Building (708 8th Street) The building was built in 1902 to house the administrative offices of the New Cache la Poudre Irrigation Company, formed to operate the No. 2 ditch which brought water to the Union Colony. The building is characteristic of late 19th and early 20th century commercial architectural styles.

Artesian Well #5 (E. side 10th Ave and alley b/n 5th & 6th Streets, Block 25) The Fifth Artesian Well Company was formed in May 1886 and was incorporated with W. Ross, owner of the Oak & Adams House at 930 5th Street, as one of the incorporators. Drilling for Artesian Well #5 began in late May of 1886 and was completed around June 16th of the same year. Water was found at 1160 feet with the drilling going as deep as 1287 feet. The first Artesian Well was drilled in Lincoln Park in 1884, and there were a total of eight wells drilled in Greeley between 1884 and 1886 due to impure surface water. The City later brought water from the mountains, and it is likely that the wells were not used frequently once the water was piped from the mountains. The well was designated in February 2001.

Baker Duff House (923 6th Street) Local contractor and builder Joseph Moss constructed this house in 1883. The house is associated with prominent local photographer Frank E. Baker, who lived in the house (but did not own it), as well as the Joyce and Lofgren families. It is also significant for the architecturally unique features of scored wooden siding with wooden quoins, which simulate stone detailing. It was designated on the Greeley Historic Register in May 2001.
Gale House (911 6th St.) This Italianate style residence was built in 1888 for C.A. Gale. It is important due to its close proximity to the Oak and Adams House and the historic downtown area.

Masonic Temple (829 10th Avenue) William Bowman designed this building for Greeley's Masonic Lodge in 1927. Greeley's Occidental Lodge No. 20 A.F. & A.M. was established in November 1870, and the group met in various locations until this temple was built, including in the Greeley Opera House from 1913 - 1927. Interesting architectural features include the gable roof with a shaped parapet wall and the oculus window and pilasters (attached columns) on the east elevation.
