The submarine base and the city
Reconstruction of the city began in1949 further away from the harbor under the direction of the architect Noël le Meresquier. The virtually unscathed bunker remained a powerful obstacle between the city and the harbor.
Batteux, the mayor of Saint-Nazaire, declared the base as central to the future development of the city. In the first phase, under the direction of the Barcelonan architect Manuel de Solar-Morales, four cells at the center of the bunker opened up and the roof was fitted with a ramp accessible to the public.
The Life, a space for emerging art forms; the Vip, hosting contemporary music events, recording studios, and an archive; the Street, the main conduit traversing the entire Bunker, connecting the various programs and creating interaction between each of the cells; and the roof and Radom.
A vertical Piranesi's shaft was created to bring natural light into the tunnel and to connect the main spaces to the upper floors and roof.
Occupying the bulk of the former submarine basin, it has been equipped minimalistically: corrugated metal ceiling; two scenic walkways; a retractable gate opening onto the harbor; a concrete floor mixed with quartz powder. The vertical walls have no treatment.
A bar overlooks the double-height space.
The roof and the radome
A large stairway rises through a hole in the bunker ceiling opening onto an experimental platform housing the radome: a geodetic dome construction that was previously in use as a covering for the strategic radar unit at the Berlin Tempelhof Airport from 1984 until 2003. Its aluminium frame makes up 298 triangles, each covered with a translucent membrane.
