Location: Brussels, Belgium
Architect: André Waterkeyn
Purpose: monument built for Expo ‘58
More info: One of the original ideas for Expo ‘58 was to build an upside-down version of the Eiffel tower, however, Waterkeyn felt that an atomic structure would be more symbolic of the era. The monument was originally planned to remain standing only six months. However, it soon became a symbol not only of the World’s Fair, but of modern architecture and Brussels. The monument stayed the same for almost 50 years.
