Suite de triangles is a work created in 2007 by Swiss artist Felice Varini. It is located in Saint-Nazaire, France. As with many of Varini's works, it is an anamorphosis, here a series of red triangles that can only be properly perceived from a single point of view. The painted elements of the anamorphosis include many buildings, up to 2 km away, that surround the port of Saint-Nazaire.
However, the complete work of art can only be seen from a certain point on the panoramic terrace on the roof of the Sous-Marin Espadon Museum (part of the former WW2 German submarine bunker).
