KXTV/KOVR/KCRA Tower

KXTV/KOVR/KCRA Tower is a 472.1-meter-high guy-wired aerial mast for the transmission of FM radio and television programs in Walnut Grove, California. Construction began on the KOVR/KCRA Tower in 1959, and the tower was completed in 1961. At that time it was one of the tallest structures in the world.

When built, it stood alone as a landmark visible from great distances, so for years it was popularly known as The Walnut Grove Tower. It is also known as Transtower. Three taller masts have since been constructed in the area that tend to be more visible because their white strobe lighting catches the eye more readily than the older tower's more traditional red lighting—though this tower is the only one painted red and white.
