March 31, 1889  – Eiffel Tower opens

On this day, the Eiffel Tower is unveiled in Paris.

When French engineer Alexander Gustave Eiffel proposed building a tower out of open-lattice wrought iron for the Paris Exhibition of 1889, few took him seriously.

However, he persisted, and when the exhibition opened on March 31, 1889, Eiffel himself raised the French flag at the top of his tower. At that time, the Eiffel Tower was the world’s tallest structure, standing at 984 feet. One of the masterpieces of 19th-century architecture, it remains largely unchanged today.
