When the plans for the Eiffel Tower were first announced, many people hated the design of the future landmark, calling it ungainly and out of step with the beautiful stone buildings of the city. But once it went up for the World's Fair in 1889, the people of Paris quickly fell in love with the tower. Today it seems impossible to imagine Paris without the Eiffel Tower, which greets millions of visitors each year who climb up its wrought-iron stairs, ride its glass elevators, and enjoy the wonderful views of the city spread out below it.

The Galapagos Islands are a chain of volcanic islands located on either side of the equator in the Pacific Ocean. The isolated location of the islands has allowed a vast number of species to develop that are original to each island, such as the blue-footed booby, the marine iguana, and of course, the giant Galapagos tortoise, which may live to be over one hundred years old. Studied by Charles Darwin during his historic voyage on the HMS Beagle, the island life contributed to his groundbreaking theory of evolution. Today the islands area popular tourist destination and a UNESCO World Heritage site.
