Architect: Émile Aillaud
Location: Paris
Year completed: 1977 

French architect Émile Aillaud was known for his smooth, abstract forms, simplified compositions, and thoughtful use of public space. While all of these traits seem positive, when used incorrectly, they can result in a misguided building. This is where the Tours Aillaud comes in. The curved buildings are clad in earth tones and windows that look like speech bubbles. Also, the rounded forms severely date the structures. Some architecture critics have even gone so far as to suggest, "If the architect was trying to depict concrete being vomited upwards from the bowels of the Earth, then he was very successful."
