McFarland State Historic Park contains an 1878 courthouse, which displays the transition between Sonoran and Anglo-American architecture. Between 1891 and 1938, the structure was used as a county hospital. The site also served as a jail in the late 1800s. The site interprets Arizona Territory history and law enforcement.

The park offers exhibits, period rooms, guided walking tours of the Florence historic district, archival access, courtroom talks for students, guided building tours for students, and picnic areas.

The park is currently closed while exhibits are being changed.
