Have you ever wondered what would happen if you walked in a straight line around the world from Charleston? 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

In our search, 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).

Dozens of results popped up, with the most populated place lying directly to our south: Guayaquil. Ecuador's largest city is home to over 3 million people, and is renowned for its coastal charm, vibrant neighborhoods, and historic sites.

The largest US city Charleston is aligned with? San Diego, California (hey, SDtoday). We won’t spoil which other cities we found. Explore for yourself.
