List of tallest buildings and structures
The world's tallest artificial structure is the Burj Khalifa in Dubai (of the United Arab Emirates). The building gained the official title of "Tallest Building in the World" and the tallest self-supported structure at its opening on January 9, 2010. The second-tallest self-supporting structure and the tallest tower is the Tokyo Skytree. The tallest guyed structure is the KVLY-TV mast.
Eiffel Tower
The Eiffel Tower was the world's tallest structure when completed in 1889, a distinction it retained until 1929 when the Chrysler Building in New York City was topped out. The tower has lost its standing both as the world's tallest structure and the world's tallest lattice tower but retains its status as the tallest freestanding (non-guyed) structure in France.
