Tower of Jewels, which rose to . The Tower was covered with over 102,000 suspended, mirror-backed Austrian
cut glass prisms, branded as "Novagem", some colored and some clear, which refracted sunlight by day and reflected 54 searchlight beams by night. Two buildings were lit from within at night, one of them an "Electric Kaleidoscope" created by a circle of 12 moving floodlight beams aimed upwards at the glass dome of the Palace of Horticulture. and also the first use of high-pressure
gas mantle lamps and of high-wattage tungsten filament lamps. South of the Tower, the Fountain of Energy flowed at the center of the South Gardens, flanked by the Palace of Horticulture on the west and the Festival Hall to the east. The arch of the Tower served as the gateway to the Court of the Universe, leading to the Court of the Four Seasons to the west and the Court of Abundance to the east. These courts formed the primary exhibit area for the fair, which included the Palaces of Food Products, Agriculture, Liberal Arts, and Education and Social Economy and surrounding the Court of the Four Seasons; and the Palaces of Transportation, Mines and Metallurgy, Varied Industries, and Manufacturers surrounding the Court of Abundance. The central court group was bookended on the east by the Palace of Machinery, the largest of all the halls built for the Exhibition, and on the west by the
Palace of Fine Arts, which survives onsite. Further west into the Presidio, down The Avenue of the Nations, were national and states' buildings, displaying customs and products unique to the area represented. The far western end of the Fair, past the states' pavilions, was reserved for live stock exhibits. At the opposite end of the Fair, near
Fort Mason was "The Zone", an avenue of popular amusements and concessions stands.
Construction Constructed from temporary materials (primarily
staff, a combination of plaster and burlap fiber), almost all the fair's various buildings and attractions were pulled down in late 1915. Intended to fall into pieces at the close of the fair (reportedly because the architect believed every great city needed ruins), the only presently-surviving building on the Exposition grounds,
Bernard Maybeck's Palace of Fine Arts, remained in place, slowly falling into disrepair. The hall, used to display painting and sculpture during the Fair, was repurposed as a garage for jeeps during
World War II. The Palace, including the colonnade with its signature weeping women and rotunda dome, was completely reconstructed in the 1960s and a seismic retrofit was completed in early 2009. The
Exploratorium, an interactive science museum, occupied the northern 2/3 of the Palace from 1969 to 2013; the city-owned Palace of Fine Arts Theater, has occupied the southern 1/3 since 1970. Several other buildings were saved immediately following the Exposition, including the California, Missouri, and Philippine buildings, which were built on government land.
Other surviving buildings Buildings from the Exposition that still stand today (other than the Palace of Fine Arts) include what is now called the
Bill Graham Civic Auditorium at Civic Center Plaza and the Japanese Tea house, which was barged down the Bay to
Belmont, California, and operated successively as a private residence, speakeasy, and restaurant. Also surviving are the one-third scale steam locomotives of the Overfair Railroad that operated at the Exposition. They had been maintained in working order at the
Swanton Pacific Railroad Society located on Cal Poly San Luis Obispo's
Swanton Ranch just north of Santa Cruz. But a forest fire swept through the area in 2020, severely damaging the railroad. The
Legion of Honor Museum, in
Lincoln Park, was the gift of
Alma de Bretteville Spreckels, wife of the sugar magnate and
thoroughbred racehorse owner/breeder
Adolph B. Spreckels. The building is a full-scale replica of the French Pavilion from the 1915 Panama–Pacific International Exposition, which in turn was a three-quarter-scale version of the
Palais de la Légion d'Honneur also known as the Hôtel de Salm in
Paris by
George Applegarth and H. Guillaume. At the close of the exposition, the French government granted Spreckels permission to construct a permanent replica of the French Pavilion, but World War I delayed the groundbreaking until 1921. The warehouse for the exposition was moved to
Fort Hunter Liggett in South Monterey County and the structure, nicknamed the "Tin Barn", has served as the base fire department for the last 30 years. After its move, it initially served as a horse barn, and since then, it has served as a gym, PX and a movie theater for the base. == Commemorations and legacy ==
