Say “Los Angeles” and most people picture movie stars. But the City of Angels has a history that’s way more interesting than its Hollywood reputation. Long before it became the entertainment capital of the world, L.A. was a dusty little settlement with an impossibly long name. It took over a century and a whole lot of ambition to turn that sleepy pueblo into the sprawling metropolis we know today.

From secret tunnels to a sewer pipe that turned into one of the most famous piers in the country, Los Angeles has quietly collected some of the best trivia of any American city. Here are 14 fun facts that’ll make you look at L.A. a little differently.

1. Its original name was a mouthful

When Los Angeles was founded in 1781, it wasn’t called Los Angeles at all. The city’s full name translated to “The town of our lady queen of the Angels on the Porciúncula River,” which is quite a bit longer than what fits on a postcard.

2. It used to belong to Mexico

Before 1848, Los Angeles was under Mexican rule, and it only changed hands after the Mexican-American War, which helped shape the diverse cultural mix the city is known for.

3. L.A. had California’s very first movie theater

Tally’s Electric Theatre opened its doors on April 2, 1902, making it the first movie theater in the entire state.

4. The internet basically started here

Long before Los Angeles became known for streaming shows, it played a part in making the internet possible in the first place. In 1969, the first message ever sent over ARPANET, the precursor to the modern internet, traveled from UCLA to Stanford.

5. Los Angeles is the only North American city to host the Olympics twice

That distinction alone sets it apart from every other city on the continent, and it’s set to make it three times when the Games return in 2028.

6. The Santa Monica Pier started out with a much less glamorous job

Today it’s one of the most photographed spots in Southern California, but it was originally built in 1909 to carry pipes that sent human waste out into the ocean. Not exactly the romantic origin story you’d expect.

7. Nobody actually lived on Hollywood Boulevard first

L.A.’s oldest surviving house isn’t anywhere near the glitz of Hollywood. The oldest house in the city sits on Olvera Street and dates all the way back to 1818.

8. There’s a hidden tunnel network under Downtown

A system of tunnels running beneath Downtown Los Angeles was once used during Prohibition to sneak people and liquor between bars and theaters. Most Angelenos walk right over them without ever knowing they’re there.

9. Marilyn Monroe had a very different job before Hollywood

Before she became a movie star, Marilyn Monroe worked at a defense factory in the L.A. area during World War II, helping assemble parts for target drones used in military training.

10. Oil built the city first

It was actually the oil industry that played the bigger role in the city’s early development, after the Los Angeles City oil field was discovered in 1893.

11. Downtown has the largest collection of old movie theatres in the country

More than a dozen historic movie theaters were built along Broadway in the 1910s and 1920s, making it home to the largest concentration of historic movie palaces in the U.S.

12. Palm trees aren’t even native

As iconic as they are in every postcard shot of the city, palm trees actually aren’t indigenous to the Los Angeles region at all. They were planted to create the image the city wanted to sell.

13. L.A.’s old rail system was once the largest in the world

Long before freeways took over, the Pacific Electric rail system was the largest operator of interurban electric railway service anywhere in the world, running 2,160 daily trains over more than 1,000 miles.

14. The Hollywood Sign almost didn’t survive

By the 1970s, the sign had fallen into such disrepair, with celebrities like Hugh Hefner and Alice Cooper contributing to restore it.
