The 1898 courthouse: architecture and historical context
The Navajo County Courthouse was constructed in 1898 — eight years after Navajo County was created from Apache County in 1895 and nine years before Arizona statehood in 1912. The building is one of the oldest surviving public buildings in northeastern Arizona and is on the National Register of Historic Places. The architecture is late-Victorian commercial style — a substantial two-story masonry structure with a flat roof, ornamental brickwork, tall narrow windows, and a center-entrance facade that opens onto Arizona Street. The building's exterior has been preserved essentially unchanged since 1898; only the original main entrance has been modified for ADA accessibility.
The courthouse served as the seat of Navajo County government from 1898 through the late 1970s, when a new modern courthouse was built nearby and county offices moved out. The 1898 building was at risk of demolition during the late 1970s but was preserved through a combination of historical-society advocacy, National Register listing, and adaptive reuse as a museum and visitor center. The renovation work preserved the historically significant interior spaces — the original courtroom, the original jail, the original administrative offices on the ground floor — while modernizing some less-significant spaces for visitor-center and museum use.
The building's location on East Arizona Street is itself historically significant. Arizona Street runs parallel to and one block north of Hopi Drive (the historic Route 66 alignment), and the courthouse was positioned to serve both the original 1880s railroad-era town center and the subsequent 1920s-onward Route 66 commercial strip. The combination of railroad-era and Route 66-era development is visible in the surrounding street grid and in the various commercial buildings that have served different economic eras across the decades.
