Star Axis

Star Axis is a massive land-art sculpture and naked-eye observatory built on a remote mesa south of Las Vegas, New Mexico.

Created by artist Charles Ross, the structure was designed around the movements of the Earth and stars. Construction began in 1976, and the finished work rises about 11 stories high and stretches roughly one-tenth of a mile across.

Exploring Star Axis

The centerpiece is the Star Tunnel, a long stairway aligned with Earth’s rotational axis and pointed toward Polaris. As you climb, different openings frame the changing position of the North Star across Earth’s roughly 26,000-year precession cycle.

Other parts of the sculpture track the movement of the Sun, stars, and Earth’s rotation, turning the entire structure into a giant astronomical instrument as much as a piece of art.

Why did Charles Ross Build a Giant Pyramid?

Charles Ross built Star Axis to turn astronomy into something people could physically experience rather than study on a page.

The structure uses tunnels, stairs, and openings aligned with Earth’s rotation, the movement of Polaris, the celestial equator, and the Sun, allowing visitors to move through astronomical cycles that normally unfold over hours, seasons, or even thousands of years. Ross’s work blends art, mathematics, geometry, and a fascination with light and the cosmos!

Fun fact: During construction of Star Axis, Ross says he woke for 30 consecutive days with the phrase “You have to enter the Earth to reach the stars” running through his head. He took it as inspiration to redesign the staircase so that it tunneled into the mesa, a change he says added 15 years to construction.

Visiting

Star Axis is located on Chupinas Mesa in San Miguel County, south of Las Vegas. The site is currently closed to normal public visitation, although limited visits are available to some supporters while work continues toward a broader public opening (supposedly coming very soon).
