Cupid's Span is a 60-foot tall stainless steel and fiberglass structure in San Francisco that resembles Cupid's bow and arrow. Completed in 2003, it was used to represent Tony Bennett's song, "I Left My Heart in San Francisco".
100 years after people the bow's string cracks and breaks, but the bow and arrow continue to stand, since the string was just a decoration.
200 years after people the arrow, which is tilted, collaspes after years of slowly increasing its lean when the ground becomes muddy. Soon afterwards, the bow also comes down, but both sturctures remain intact, since both are made of stainless steel.
