The main courthouse is the Riverside Historic Courthouse . This landmark , erected in 1903 , was modeled after the Grand and Petit Palais in Paris , France . The courthouse , designed by Los Angeles architects Burnham and Bliesner , has a classical design – including a great hall that connects all the departments ( courtrooms ) . In 1994 , the courthouse was closed for seismic retrofits due to the 1992 Landers and 1994 Northridge earthquakes . The courthouse was reopened and rededicated in September 1998
