Eiffel Tower

The Eiffel Tower is a famous French monument built in 1879 in Paris, Earth, and one of the rare buildings to not have been destroyed various times over the years. Numerous people celebrated New Year's Eve of both 1999 and 2999 around it.

Changes
The Eiffel Tower seems to have suffered several changes since the beginning of the 31st century. When the Planet Express crew went to Paris while looking for Project Satan, it was stationary. However, when Pazuzu was telling his son the story of his freedom in 3003, it was hovering. The Tower was also moved from its usual location in 3010, when the Thubanians invaded Earth, and was replaced by the Big Ben, which itself was replaced by the Statue of Liberty. Additionally, it looked different then than during its other appearances.
