To visit a “top secret” site is a dream for many James Bond fans. Become a secret agent the time of a visit led by the volunteers of ATOMES and enter into the history of the Cold War by exploring the corridors of the NATO Fort.

Everything began in 1953 in a context of Cold War, international tensions and a project: the G work was born… Well, not exactly, since this site was originally the underground radar station of the French air force, concealed under the Salbert Mount. This was a heavy investment at the time for an activity which in the end only lasted a year.

Fenêtres intéreurs

Since May 2016 it’s been possible to visit the NATO Fort during European Heritage Days. For those who cannot wait Belfort Tourisme organises guided tours of one and a half hour. This unusual place is very popular with the visitors of the Territoire de Belfort in search of originality. The renovation of the G work is still underway.
