Seattle

Seattle's Space Needle turns 50 on Saturday. Originally built as a tourist attraction for the city's 1962 World's Fair, the structure was meant to evoke the future. Now the future is here, and the Needle has become the city's favorite antique.

Peter Steinbrueck traces the tower's lineage to an abstract sculpture that sits in his office. Steinbrueck is an architect and former City Council member, and the sculpture used to belong to his father, Victor, also an architect.
