AT&T Switching Center, Telecommunications tower in Bunker Hill, Los Angeles, United States.
The AT&T Switching Center stretches 137 meters into the Los Angeles skyline, featuring a steel microwave tower and white tile exterior with black granite accents.
Constructed in 1961 by architects John and Donald Parkinson, this structure became the highest building in downtown Los Angeles due to its microwave communications tower.
The entrance displays an extensive mosaic mural by Anthony Heinsbergen that incorporates actual telephone equipment to illustrate the evolution of communications networks.
The 17-floor center manages over 1.3 million phone lines across multiple area codes, serving as a primary telecommunications hub for the Los Angeles region.
The building houses technology for the NSA Fairview surveillance program while its corner windows feature metal screens and distinctive louver-like decorative elements.
