The microwave tower at AT&T’s Madison Madison Complex Tandem Office, the central telephone and data switching office for Downtown Los Angeles. When it was built in 1961, the 17-story office with a tower that reached 137 meters was the tallest building in Los Angeles. The construction of much taller skyscrapers since then has demoted the tower to 29th place. The tower and its array of “horn” antennas remained in use until 1993, when fiber optics replaced the microwave links.
This view from Pershing Square also includes a portion of Frank Stella’s mural Dusk, on the headquarters building of the Southern California Gas Company.
