This neoclassical masterpiece is the monumental heart of the Civic Center. If you look closely, you’ll see it includes all kinds of historical styles and references. At the center, a base of Roman arches supports a Greek Doric temple motif above, with a massive dome behind. The dome, no doubt, was inspired by St. Peter’s Basilica in Rome. The interior is open to the public during regular hours, and inside you will find tributes to former mayor George Moscone and county supervisor Harvey Milk, both assassinated within its walls.
