Allouis longwave transmitter, Radio transmission facility in Allouis, France
The transmission complex features two metal towers reaching 350 meters in height, making them among the tallest structures in France.
The original transmitter, established in 1939, was destroyed during World War II and rebuilt in 1952 with enhanced broadcasting capabilities.
The station transmitted France Inter radio programs across the nation until 2016, serving as a primary source of information for French citizens.
Since 2017, the facility exclusively broadcasts the ALS162 time signal, which synchronizes numerous public clocks and devices throughout France.
