A **radome** is a large, dome-shaped structure designed to protect sensitive equipment like **antennas** from weather while allowing **radio waves** to pass through. In the middle of a Breton field, just a few hundred meters from the sea, stands a massive white sphere with a diameter of 64 meters. This unusual structure, known as the Pleumeur-Bodou radome, has long captured the attention of hikers and local residents. It is not just an odd sight, but also a symbol of one of the most impressive technological achievements of the 20th century. Built between 1961 and 1962, the radome housed the PB1 antenna, a massive 340-ton structure that was transported to France by ship from the United States. This antenna was part of a historic moment in 1962 when France, using the Telstar 1 satellite, captured the first live transatlantic television images—just one minute before the British achieved the same feat. The event marked a breakthrough in global communication and placed France at the forefront of a technological race during the Cold War. The construction of the radome was a massive undertaking, involving up to 1,250 workers who worked around the clock to complete the project under tight deadlines. Inside the radome, the PB1 antenna was assembled on a circular rail, resting on a massive concrete base. The structure itself was made of a thin, fabric-like material called **dacron**, which was kept inflated by constant air pressure. This seemingly fragile material was able to protect the massive antenna from the harsh weather of Brittany while allowing radio waves to pass through unimpeded. The antenna operated for 23 years before being retired in 1985, eventually replaced by newer technologies like undersea fiber-optic cables. Today, the Pleumeur-Bodou radome is a historical monument and home to the Cité des Télécoms, a museum dedicated to the history of telecommunications. Visitors can explore the site and reflect on the significance of that fateful night in July 1962, when the world was brought closer together through the power of technology. Though the antenna is now silent, the radome continues to inspire awe and curiosity, standing as a testament to an era when technological innovation had the power to bridge continents.
