The Dillon School Campus includes a unique collection of educational buildings from different periods, each representing the pedagogical and architectural styles of its age. The first building constructed on the campus was the 1896 Dillon Graded School, built in the Italianate style as a statement of the community’s commitment to educating its children. Auditorium and gymnasium additions built in 1936 display a striped classicism typical of Public Works Administration funded building projects. The 1957 cafeteria addition reflects then-prevailing thinking that one-story schools with window walls for light and circulation were best. The complex was listed in the National Register of Historic Places in 2014.
