Save the Palace of Fine Arts? In the 60s, SF wasn't so sure.

From an article published on SFGATE a few years ago, the 1915 Panama-Pacific International Exposition buildings were constructed from temporary materials, primarily a combination of plaster and burlap fiber. Almost all the fair's various buildings and attractions were razed in late 1915. The only surviving building on the exposition grounds, Bernard Maybeck's Palace of Fine Arts, remained in place, slowly falling into ruin. It was re-purposed as a garage for Jeeps during World War II.
