Before Atlanta was a city, the Zero Mile Post marks city’s start as a rail stop called Terminus

The Zero Mile Post, used to mark the founding of Atlanta, has been around since 1837

Q: I’ve been looking for a marker called the Zero Mile Post. Can you tell me where it’s located?

—Dennis Withers, Atlanta

A: The Zero Mile Post is beaten up and weathered.

Chunks are missing and dark stains partially obscure the letters and numbers chiseled into its side.

Or at least that’s how it appears in photos from the past 10 years.

The Zero Mile Post is perhaps the oldest landmark in Atlanta, a reminder of the time when the city was merely a spot where railroads were destined to meet.

It’s also one of the least seen.

The Zero Mile Post stood for years near the rail lines in and under downtown Atlanta. Then it was locked away in a vacant building near Underground Atlanta, which meant folks couldn’t visit it. The facility under the Central Avenue viaduct was surrounded by parking lots and was once used by the Capitol police.

In 2018, the Zero Mile Post was moved a number of miles north to Buckhead and its new home at the Atlanta History Center.

UPDATE Aug. 2018: The building is scheduled to be torn down and the marker may move

UPDATE to the UPDATE Oct. 2018: Zero Mile Post moved to Atlanta History Center (and not everybody is happy about that)

If you’re a native Atlantan and you’ve never heard of the Zero Mile Post, don’t feel bad. I hadn’t either before I started writing this column several years ago.

Even though the Zero Mile Post has been around since 1837 – before Atlanta was called Atlanta — it's a little-known object and absent from the must-see lists of all the folks who are here to check out the World of Coca-Cola or Georgia Aquarium.

That doesn’t detract from its significance.

“It’s a unique landmark,” said Paul Melvin, the director of communications for the Georgia Building Authority, which owns the building surrounding the Zero Mile Post.

The post was installed to mark the end of the Western and Atlantic Railroad, which linked the area with Chattanooga.

“W&A R.R. 0 0” is inscribed on one side of the stone marker.

The town that grew up around it was called Terminus.

That became Marthasville in 1843, which several years later was renamed Atlanta.

The Zero Mile Post is shown with a brand new historic marker in this photo from 1958. The landmark used to be exposed beneath a downtown viaduct and was open to the public. Today, it sits inslide a government building that remains locked. (AJC Archive at GSU Library / AJCP142-020I)

About the marker post

An accompanying historical marker states: “A new City Charter approved February 28, 1874 redefined the corporate limits as a circle one mile and a half in every direction from this mile post.”

The post is about three feet high and each of its four sides measure 12 inches. The marker shows plenty of signs from being unprotected from the elements for nearly a century, before the viaduct was built in 1929.
