I briefly drove past here at the end of our earlier trip in 2017 and took a quick single picture. But when we returned in 2023 we parked and took our time to walk around the area.  Very pretty area in the northwest corner of the city. 

The Palace of Fine Arts is a monumental structure located in the Marina District of San Francisco, California, originally built for the 1915 Panama–Pacific International Exposition to exhibit works of art. It was constructed from concrete and steel. It is the only structure from the exposition that survives on site.
