Sillon de Bretagne is a 32-storey brutalist skyscraper completed in 1969 in Saint-Herblain, a suburb of Nantes in France's Loire-Atlantique department. Rising 97 metres, it was the tallest building in France upon completion. Designed by Jean Boquien and Georges Ganuchaud, the structure is distinguished by its massive 425-metre width and footprint of 36,200 square metres, making it one of Europe's largest buildings by volume. Originally conceived as mixed-use accommodation, it houses living and office space for approximately 3,600 people. Its rooftop hosts the antenna system for a Digital Audio Broadcast transmitter operated by GRAM (Groupement des radios associatives de la métropole nantaise).
