The Cadillac Ranch is a public art installation located just outside the city of Amarillo in the Texas Panhandle. Created in 1974 by the art collective Ant Farm, it consists of ten vintage Cadillac cars buried nose-first in a field at an angle that matches the slope of the nearby prairie. The installation was originally commissioned by local millionaire and art patron Stanley Marsh 3.

The artwork is designed as a form of interactive and evolving expression. Visitors are encouraged to spray-paint the cars, which means their appearance is constantly changing as layers of graffiti accumulate over time. This participatory aspect has made Cadillac Ranch one of the most recognizable examples of roadside art in the United States, reflecting themes of consumer culture, Americana, and artistic freedom.

Today, Cadillac Ranch remains a popular stop along historic Route 66, attracting travelers, photographers, and art enthusiasts. Its open-access nature and ever-changing surface make each visit unique. Blending pop art, roadside culture, and public participation, it stands as an iconic and unconventional symbol of Texas creativity.
