The adventure of the 30-foot Tetrodon begins with Except ... (territories) the association's project through this passage, infranch. An exploration of the territories from the Étang de Berre to the Golfe de Fos, between habitats, industries and nature.
The association agreed to receive for one symbolic euro in December 2011 this mobile and modular habitat, identified as a Tetrodon by the historian architect Thierry Duroussea, the last in the region.

Inhabitable space, the Tétrodon will offer residences to artists, from the Etang de Berre to the Golfe de Fos. These residences can be extended to experts, researchers, architects, designers, participating in the creation of a laboratory / observatory of the territories.
The modular spaces of the Tétrodon are adaptable: assembly of panels closing the hulls to create an indoor exhibition space, exterior extension by light structures such as canvas ...
The Tétrodon can also be used to accommodate groups for the start of walks, the organization of artistic workshops not requiring significant equipment.

A little history.
This Tétrodon came from an order from Sonacotra in 1972 for 32 6-meter models to house the workers building the SOLMER (Arcelor Mittal) steel plant in Fos-sur-Mer.
This 10 meter model is the only result of this order.

In return, the association decides to renovate it in order to make it its flagship project, a perennial place intended to welcome visitors, walkers, and artists like a peri-urban refuge. The idea of ​​locating it along the GR2013 then emerges when the association participates in 2013 in Marseille European Capital of Culture and contributes to the realization of this first peri-urban GR. It was labeled 'Patrimoine XXème' by the DRAC in 2012, and became the property of the City of Martigues in 2019 after its restoration.
