The Parc du Radôme
Pleumeur-Bodou
About
The Radôme, a technological jewel in the crown for France during the 1960s, a symbol of the modernism of Brittany and an iconic image of Pleumeur-Bodou, is composed of a dome 64 m in diameter and 50 m in height, which houses a horn antenna weighing 340 tonnes. Built in the early 1960s, this device is considered pioneering in the history of space-based telecommunications. In 1962, it was used to relay live televised images from the United States for the first time, via the Telstar satellite. It is now classed as a historical monument and is the flagship of the Cité des télécoms, a key location in the Parc du Radôme. You can explore the site using the footpath, admiring the pink granite outcrops, and enjoying the park’s facilities and events: the Cité des télécoms, the Planétarium de Bretagne (planetarium), the Village Gaulois (a reconstructed Gaulish village), the Arboretum, etc.
