Eiffel Tower Paris France

The Eiffel Tower, La Tour Eiffel in French, was the main exhibit of the Paris Exposition — or World's Fair — of 1889. It was constructed to commemorate the centennial of the French Revolution and to demonstrate France's industrial prowess to the world. "Although at the beginning it was seen as 'the ugliest building in Paris,' soon it became the symbol of the city," said Tea Gudek Snajdar, an Amsterdam-based art historian, museum docent and a blogger at Culture Tourist.
