The structure, with its Greco-Roman grandeur, has become an icon in San Francisco since the event and defied its temporary fate due to its popularity. The Palace of Fine Arts underwent reconstruction in the 1960s using more permanent materials. Nowadays, it still hosts various events and remains a valuable architectural treasure in the city.
