It is located south of Steubenville and just east of Hillsboro along Wilson Avenue.

[2] The community was originally laid out in 23 lots on top of a local hill, the name "Altamont Hill" dating back to before the Civil War.

In 1899, the Steubenville, Mingo & Ohio Valley Traction Company (later the Steubenville & Wheeling Traction Company) built an electric street railroad from Steubenville to Brilliant and Mingo Junction going over Altamont Hill (with a station in the Atlamont community).

The Altamont line was rarely used though, due to the high grade, and after seven years was abandoned in favor of a lower grade junction that was built around the hill.
