In 1867, the Superior Court of California erected the first Fresno County courthouse in Millerton. Construction cost $24,000 and used locally sourced granite blocks, some of which weighed over a ton. The two-story building contained a jail, the offices of the Sheriff, assessor, treasurer, and clerk. The courtroom occupied most of the second floor. After the devastating floods in 1874, residents voted to move the county seat to Fresno. The courthouse was repurposed and used as a schoolhouse for those who remained nearby. With the completion of the Friant Dam in 1944, the building was carefully dismantled, the blocks were marked, and stored in the nearby town of Friant. In 1965, the courthouse was reconstructed on Mariner's Point.
