Centre émetteur de Fontbonne, Radio transmission center in Peille, France.
The Fontbonne transmission center sits at 800 meters altitude on Mont Agel slopes, overlooking Monaco with multiple broadcasting antennas and technical facilities. The facility operated with several powerful transmitters, including two 100 kW and two 500 kW units, providing broad coverage across the region.
Radio Monte-Carlo established this broadcasting center in 1946, starting with a 10 kW medium wave transmitter operating at 205 meters wavelength. The facility later grew into one of the region's most significant radio transmission centers.
The site broadcast religious programs from Trans World Radio in more than twenty languages, reaching listeners across Europe and the Middle East. These transmissions shaped radio listening for millions of people over several decades.
The site sits on a mountain location with unpaved access and can be hard to reach depending on weather conditions. Visitors should wear sturdy shoes and proceed with caution, especially during wet or windy weather.
Since 2013, the partially decommissioned site houses elephants from Lyon Zoo under Princess Stephanie of Monaco's initiative. This unexpected reuse links the radio facility's past with a modern wildlife conservation project.
