France
The 186th tallest tower in the world
The Perret tower, originally called La tour pour regarder les montagnes ('The tower for looking at the mountains'), is an observation tower in Grenoble, in the Paul Mistral public park. It was the first tower built of reinforced concrete in Europe. In 1998 it was officially declared a national heritage site. It was built for the International Exhibition of Hydropower and Tourism where it was the orientation tower and the symbol of the exhibition. Nowadays it is the last vestige of this exhibition.
