Ha! Ha! Pyramid
La Baie, Canada · built 1998
The Ha! Ha! Pyramid (Pyramide des Ha! Ha!) is a contemporary art monument commemorating the Saguenay flood of 1996. Located in the district of La Baie in Saguenay, Quebec, the pyramid was named after the nearby Ha! Ha! River. Conceived as a form of therapy to help residents recover from the traumatic events of the flood, it is covered in 3,000 yield signs, based on the similarity of pronunciation of the French words for "to yield" (céder [se.de]) and "to help each other" (s'aider [sɛ.de]).
