The Eiffel Tower, a wrought-iron lattice tower on the Champ de Mars in Paris, France, is named after its designer, Gustave Eiffel, whose company designed and built it. Construction began in 1887 and completed in 1889 for the World's Fair. Initially controversial, it's now an iconic global symbol of France and one of the world's most visited paid monuments. Its height, including its antenna, exceeds 1,000 feet. Three levels offer stunning city views, restaurants, and shops.
