San Francisco Facts

Test your knowledge with these interesting San Francsico facts:

  • Chinatown: San Francisco was the birthplace of the fortune cookie. That's right; these sweet and crunchy goodies are not exactly Chinese. In fact, they were invented by the Hagiwara family, of Japanese origin, to serve at the Tea Garden in Golden Gate Park. Today, thousands are mass produced at the Ross Alley factory in Chinatown.
  • Golden Gate Bridge: Another interesting fact about San Francisco is that the Golden Gate Bridge is named after Turkey. John C. Fremont called this area near the northern tip of the city, Crysopylae, because, to him, it looked similar to Golden Horn in Istanbul. The quintessential red bridge that crosses the Bay was the longest of its kind in the world back in 1937, when it was first opened to traffic. Each tower on the bridge has 300,000 rivets.
  • Alcatraz Island: Alcatraz Island was named for a group of birds. Long before it was a prison, Juan de Ayala of Spain, discovered the island in 1775. He named it Las Isla de los Alcatraces, which loosely translates to Pelican Island. Alcatraz then, as is now, was rocky and had little vegetation. This made it a perfect habitat for sea-loving avians.
  • Union Square: This popular tourist site wasn't always so classy. These days it is home to some of the priciest real estate in the city, as well as stores like Louis Vuitton. However, it used to be called Morton Street, and it was home to houses of ill repute. It got so bad that even law enforcement officers were wary to visit the area.
  • Mission Dolores: The oldest building in the city has been around since 1791. Mission Dolores, located at 3321 16th Street, is a whitewashed church, which survived two major earthquakes, plus a 2000 attack by powderpost beetles.
  • City Hall: The famous building has quite a history. Although not the capital of the state of California, San Francisco, boasts a large domed city hall reminiscent of many state houses. The building was the site of the famous wedding between Joe Di Maggio and Marilyn Monroe, and a famous murder. It was where Dan White shot activist Harvey Milk in 1978.
