The school's current building was completed in 1927 at a cost of $350,000.

Local Architect Sidney G. Frazier designed the school to resemble a French chateau.

[3] Extensive remodels in 1958, 1974, 1994, and 2000 dramatically changed the interior and the campus, but the front remained virtually the same and has become known as "The Castle".

[4] The school building was listed on the National Register of Historic Places in 1999.

[3] The name of the school was changed in 1965 to Greeley Central, under the leadership of principals Paul S. Gillespie, Robert S. Gilcrest, Wendell T. Blight, Wendell K. Beard, Henry C. Jensen, Wendell Wilson, Robert W. Turner, Franklin H. Bressler, Rex W. Hester, Cloyd MacBernd, John Lepetit, John "JC" Christensen, Jon Helwick and Mary Lauer.
