Perret tower, Observation tower in Paul Mistral Park, Grenoble, France.
The 95-meter concrete tower features eight solid pillars with ring lines, providing structural stability and an octagonal shape at its base.
The tower opened on September 6, 1925, during the International Exhibition of Hydropower and Tourism, with Prime Minister Paul Painlevé attending the ceremony.
The construction represents a significant advancement in architectural methods as the first reinforced concrete tower built in Europe during the 1920s.
Two elevators and a spiral staircase lead to a circular terrace at 60 meters, offering views of Grenoble and the surrounding mountain ranges.
The prefabricated elements used in construction came from Notre-Dame du Raincy church, demonstrating early practices of material recycling in architecture.

Grenoble displays architectural developments from the medieval period to the present day. The medieval Notre-Dame Cathedral stands in the historic center, while the Art Museum offers modern exhibition spaces. The city includes the Tour Perret, a cylindrical tower building from the 1920s, and the Garage hélicoïdal, a spiral parking structure from the same era. Religious buildings such as Saint-Louis Church and Saint-Bruno Church represent different stylistic periods. The Sainte-Cécile Convent and the Palace of the Parliament of Dauphiné show historic administrative and ecclesiastical architecture. The Bastille fortress overlooks the city and can be reached by cable car from Quai Stéphane Jay. The Hôtel de Lesdiguières and the Old Episcopal Palace document aristocratic residential culture. Paul-Mistral Park forms a large green space containing Lesdiguières Stadium and the Alpexpo conference center. The Saint-Laurent Bridge crosses the Isère River, while the Sainte-Claire market halls house daily commerce. Vizille Castle lies outside the city in the commune of the same name. The Musée dauphinois and the Museum of Resistance and Deportation present regional history, complemented by cultural facilities such as the MC2 cultural center and Le Magasin des horizons.
