I have a tendency of knowing random facts and useless information. Oklahoma City is basically my playground for this habit. Like, I love a good “did you know?” moment, even if my kid and husband are not as impressed by a neighborhood history lesson about an old trolley line as I am.
But if you want some weird and fun Oklahoma City facts that are actually kid-friendly and worth pulling out at dinner, here you go.
1. There are underground tunnels in downtown OKC.
Yes, we have a legit underground pedestrian tunnel system downtown. It was originally built to connect buildings so people could move around without dealing with weather, traffic, or summer heat. It stretches about a mile and covers more than 20 square blocks.
Fun idea: Make it a mini scavenger hunt. Grab a snack, walk a section, and let your kid pretend you’re on a “secret mission.” If you want to plan your path, this map shows where to enter and how the tunnels connect.
2. The Oklahoma State Capitol has oil history literally on the grounds.
Oklahoma’s State Capitol grounds had active oil wells, which is a sentence that sounds fake until you realize . . . it’s Oklahoma. The Oklahoma Historical Society even calls out that the Capitol is the only Capitol grounds to have had active oil rigs, with oil production on the grounds ending in 1986.

3. Downtown manhole covers can double as “you are here” maps.
Next time you’re downtown, look down. Some manhole covers include a map of downtown and a little marker showing where you are standing. It’s like Google Maps, but in cast-iron form. This will come in handy to turn a normal walk into a low-effort adventure.

4. OKC has a museum devoted to pigeons.
Yes, pigeons. Not “birds,” not “nature.” Specifically, pigeons. The American Pigeon Museum & Library is here in Oklahoma City, and it’s exactly what it sounds like.
5. The world’s first parking meters were installed in Oklahoma City.
The first parking meters were installed in downtown OKC on July 16, 1935. So, the next time you’re feeding a meter coins or tapping your card, just know OKC helped start that whole thing. (Thanks for that, I guess?)
6. The shopping cart got its start in Oklahoma City, too.
The first shopping carts were introduced at an Oklahoma City grocery store in 1937 by Sylvan Goldman. People hated them at first, which feels hilarious now because I cannot imagine grocery shopping with my child without one.
7. One of the oldest painted objects in North America is in the OKC Metro.
The Cooper Bison Skull is considered the oldest known painted object in North America. It’s exactly what it sounds like: a bison skull with a red zigzag painted on it that is roughly 10-11,000 years old. You can see it at the Sam Noble Oklahoma Museum of Natural History in Norman.
8. OKC was basically sonic-boom central in the 1960s.
In 1964, Oklahoma City was used for supersonic flight testing. Residents experienced repeated sonic booms over a long stretch of time, and the booms were intense enough to cause damage to buildings.

9. Oklahoma has the longest drivable stretch of Route 66, and it runs through the OKC area.
Route 66 runs for roughly 400 miles across Oklahoma, which is the longest drivable stretch of any state.
10. The OKC Zoo was first established in 1902 with just one white-tailed deer.
It was Oklahoma’s first zoo and was located at Wheeler Park. It didn’t stay small for long. Donations started rolling in, including wolves, eagles, mountain lions, and bobcats. Seven years later, the zoo had grown to 125 animals. After flooding forced it to close in 1923, it reopened in 1924 at its current home in Lincoln Park.
