Gustave Eiffel built his iconic structure in 1889 to celebrate the hundredth anniversary of the French Revolution. There’s no better way to celebrate your arrival in the City of Lights than by walking up the towering symbol. Go at night when it’s a little bit cooler and take your time making the ascent to the 2nd stage. From here, an elevator brings you to the 1,063-foot high top floor, where you have views of the entire city. The tower sparkles with light in the summer for five minutes, starting on the hour. So stick around to catch this free entertainment.
