A temporary exhibition on the theme of algae
Since January 15, 2026, the Roullier Endowment Fund has also been hosting a temporary exhibition in the building’s lobby dedicated to algae and their properties, titled “When Algae Touch Us.”
This exhibition showcases algae and their crucial importance in the fields of animal and human nutrition, for terrestrial and marine ecosystems, as well as the potential they offer in various industrial sectors that impact our daily lives.
Two artists from Saint-Malo are also presenting their works around the central structure of the exhibition: cyanotypes created using algae.
Visit the exhibition
The exhibition “When Algae Touch Us” will be open to the public for self-guided tours Monday through Friday from 10 a.m. to 12 p.m. and from 2 p.m. to 4 p.m. during the Easter school break, from April 13 to 24, 2026.
