Trivia: What world-famous museum is covered in titanium?
Guggenheim Museum Bilbao
Art Institute of Chicago
Correct Answer: Guggenheim Museum Bilbao
So why is this answer correct? : Architect Frank Gehry covered the famous Spanish museum in 33,000 titanium sheets after he saw the way the material behaved on the wall of his office. Constructed between 1993 and 1997, the titanium sheets reflect the changing weather conditions. This gives the building a different appearance depending on the day, time, and weather.
