Have you ever wondered what would happen if you walked in a straight line around the world from San Antonio? Wonder no longer, wanderer. Let us introduce you to LatLon Connect, an online tool that allows users to explore cities across the world that share the same latitude and longitude.

Here’s how it works

Head to the site and type in any city you like.
Follow the blue lines in any direction to see which other cities are highlighted. Those are the ones directly in line with your original destination.
Bonus: The settings button at the top of the screen allows users to tweak the results, meaning you can look for cities with smaller or greater populations, and you can expand the buffer distance — altering the number of cities that will show up.

Here’s what we found

We stuck with the default settings, looking for places with 100,000+ people with a buffer zone of 6.21 miles (that’s 10 kilometers).

In our search, 15+ results popped up, with one place that caught our eye lying on the other side of the world: the Chinese city of Zigong, pictured above. As of recent estimates, there are more than 2.5 million people living in the city which is renowned for its salt manufacturing history + industry, as well as the large amount of dinosaur fossils found in the region.

The largest US city the Alamo City is aligned with? Wichita Falls in North Texas. We won’t spoil which other places we found — explore for yourself.
