La tour Perret, premier gratte-ciel en béton armé d’Europe, renaît à Grenoble après 60 ans de fermeture

The Tour Perret in Grenoble, Europe's first reinforced concrete skyscraper, will reopen to the public on July 11, 2026, after being closed since the 1960s. Designed by Auguste Perret in 1925 for the International Exhibition of White Coal and Tourism, the 95-meter tower has undergone a complex restoration led by heritage architect François Botton, addressing water infiltration and corrosion while preserving its original character.
