It was built for the 1915 Panama-Pacific International Exposition which included exhibits in Education, Liberal Arts, Manufactures, Varied Industries, Agriculture, Food Products, Transportation, Mines and Metallurgy and the Palace of Machinery according to Wikipedia. As a secondary purpose, it was also to celebrate the finishing of the Panama Canal and the resurrection of San Francisco after the devastating 1906 earthquake.
After the exposition, it was scheduled to be torn down, but luckily locals petitioned to have it saved.
Over the years, it became in a state of disrepair and in 1964 parts of the palace was demolished and recreated.
Today it is a popular tourist attraction and a scenic location for wedding photos.
