The Eiffel Tower is truly a spectacular engineering feat and accomplishment courtesy of the 19th century..the old world. The Tower wasn't supposed to remain after the World's Fair, but here it was, 120+ years later. When I was in Paris in July 2014, the top level observation deck was closed, so my brother and I went up to the next-highest level. The wind was incredible, it was hard to stand upright with the currents rushing through.
Maybe one day, I will return to Paris, but I don't think the same city I saw still exists.
