Architect: C.Y. Lee
Location: Shenyang, China
Year completed: 2001 

Taiwanese architect C.Y. Lee has many accomplishments to his name, including designing the world's tallest building (at time of completion, 2004). Unfortunately, Lee was also the man behind one of the world's ugliest buildings, according to Time Magazine: Fang Yuan Building in Shenyang, China. The building was designed to look like an old Chinese coin, which it accomplishes perfectly, but not without also being a strange addition to the city.
