About the Old Maricopa County Courthouse
Old Phoenix City Hall and the Maricopa County Courthouse form a historic building complex in the center of Phoenix, Arizona, which also goes by the name County-City Administration Building. Two buildings are joined together there, with the same architecture. County and city worked together on it, and the "monumentally scaled" result fills a full city block. In 1927 county voters approved $750,000 in bonds for the project, and Phoenix voters backed a separate $450,000 bond for the city hall portion.
Edward Neild of Shreveport designed the courthouse with the Phoenix firm Lescher & Mahoney, and the Los Angeles firm Edwards, Wildey and Dixon was the general contractor. The plan is an H, measuring 70 m by 40 m (230 by 130 ft). A six-story central tower dominates, with seven pronounced vertical bays. At a dedication ceremony with the building half completed, a granite cornerstone from Arizona was laid and John Philip Sousa conducted the Marine Corps Band. The city and county took possession on June 23, after construction that cost $1,200,000.
The city and the county each had offices in their own portions of the building, and a jail occupied the fifth and sixth floors. The city's Justice of the Peace and the county's Superior Court were both based there. Ernesto Miranda's first trial was held there, a case that eventually led to the Supreme Court's Miranda v. Arizona case in 1966. Many county functions moved out to new facilities completed in 1964, and in 2012 a justice museum run for the county opened in a cell block on the sixth floor.
